Are you looking for the best grinder for your herb? BestGrinder.net was created to give you insights on what to look for in a non-toxic, safe, and durable grinder. Don’t be fooled by cheap grinders at gas stations and head shops: they can be dangerous. Consider buying an herb grinder online, you’ll save money compared to buying one in a store and the number of different weed grinders for sale online far surpasses what you’ll find in your local head shop. Our site will walk you through what an herb grinder is, what the best grinders have in common, what herb grinders you should avoid, as well as the top 3 best grinders available right now online (click here to skip to the ratings).
From Golden Gate Grinders to Phoenician Engineering, BestGrinder.net has done more herb grinder reviews than any site on the web. So we were surprised when we found a prominent grinder brand that seemingly slipped through our grinder reviewing fingers. This is the case when it comes to Masterdam Grinders. Founded in Amsterdam, Masterdam has been putting out quality herb grinders since 2014 and is a well established brand, selling grinders on the Amazon marketplace, Amazon UK, and other online and offline shops around the globe.
Let’s dig deeper and see what exactly Masterdam grinders offer that help them stand out from other herb grinder brands in what has become a very competitive market.
One thing about herb grinders is that almost all of them seem to have a similar design and shape. There may be slight variations between each model in terms of teeth shape, size, number of pieces, etc., but at the end of the day they use the same basic principals to grind your herb. This entails putting the herb in the top chamber of the grinder, and turning the lid so that the teeth grind your stash to perfection.
In general, I go by the mantra of if it isn’t broke, don’t fix it, but that doesn’t mean that the herb grinder market couldn’t use some fresh ideas. For any readers would like a new take on herb grinding, the folks at PenSimple have got you covered. They have completely reimagined the herb grinder and come up with the PenSimple Grinder. It looks totally different than your run of the mill four piece aluminum grinders, and because of this has some unique features.
As with the namesake of the PenSimple, the shape of this grinder is akin to a pen. This makes it easy to hold and manipulate so that you can aim the herb with precision. Dimensions for the PenSimple are 7″x1″x1″ with a weight of only 4.3 ounces, making it very lightweight compared to typical aluminum weed grinders.
There are four pieces that attach with the PenSimple Grinder. As with standard grinders, the PenSimple has a grind chamber made up of a lid with teeth and bottom with holes to allow the ground herb to fall through. With PenSimple there are only a few small teeth on the lid, but none on the bottom part of the grind chamber, like you see with typical herb grinders.
It is important to realize that the PenSimple does not grind your herb for you. This is still a manual process.
What it does do is help to dispense the ground herb out of the tip making it easier to get the herb in your joint or bowl without spillage. With a simple push of a button your ground up stash is neatly dispersed with pinpoint accuracy. I love this feature, and is certainly a step up from typical grinders where you have to use your fingers or scraper tool to manipulate the herb.
PenSimple Grinders are made of aircraft-grade aluminum, meaning this thing is built to last. We are glad to see PenSimple use such quality materials on their grinders as it shows they take quality seriously. Another positive is that it doesn’t appear that PenSimple’s design requires any glueing of components, making it less likely that any individual part will break loose.
Three Different Grinder Modes
Unique to the PenSimple Grinder is the flexibility of having three distinct grinder modes. The three grinder modes are full, maximum-storage, and direct-grind.
This is default mode of the PenSimple. Load the herb in the grinding chamber, and once ground it is ready to be unleashed at the push of a button.
For when you are traveling, or on a hiking trip having the maximum amount of herb ready to go is a must. Maximum-Storage Mode allows you to store up to 3 grams of your finest herb by removing the top and bottom grind teeth. In this mode you cannot grind any additional herb.
Direct Grind Mode
Take out the storage compartment and then you have an efficient grinding machine. This is perfect for when you want to keep a small stash fresh and grind on the go. This mode holds up to .25 grams, but can be ground on command and still dispensed using the electric point and shoot tip.
What PenSimple Should Improve
In the future, PenSimple should strongly consider adding an electric element to the herb grinding process. Having both an electrical grinding process and the automatic dispensing tip would go a long way to set the PenSimple apart.
Another issue with the PenSimple is that the 1 inch diameter design creates an environment where it is easy for herb to clog the unit. PenSimple will have to choose between keeping their grinder portable-friendly with a frequent cleaning requirement, or to make the diameter larger meaning the grinder would become slightly less portable.
PenSimple has made some bold innovations to the herb grinder, and as such you can expect to pay more for this grinder than your average four-piece aluminum grinder. At $60, the PenSimple is not a bargain, but is cheaper than premium American Made grinders like Phoenician. This is a reasonable price point for this product.
The Final Grind
PenSimple has changed the herb grinder game with its point and shoot design. This certainly makes filling your bowl easier than ever before.
We wish that PenSimple would have added an electric grinding component, and are surprised that the actual grinding process is still manual.
Whether this is a good choice for you will depend on how much you value the point and shoot electric dispensing feature. If this is a big deal to you, then the PenSimple is really the best choice. However, for those who care equally about other functions like storage capacity, grind quality, and grinder jamming, we recommend you look at conventional high quality grinders.
One of the hottest selling herb grinders to hit the market in recent months is the Kozo Herb Grinder. This grinder has been selling so well that it appears that Kozo has had a hard time keeping it in stock. The reviews for this herb grinder are also stellar leading to a good reputation.
At BestGrinder.net we like to dig a little deeper to see if the sales volume and reviews match up with the quality. Let’s take a close look at the Kozo Grinder’s pricing, features, and quality.
The Kozo Grinder is no doubt a good looking herb grinder. I personally like the black and white lines that are included as design elements on the outside of the Kozo.
Another feature on the outside of the Kozo Herb Grinder is the indents that span vertically from the top of the grinder to the bottom. These are part of the herb grinder to enhance the grip so that you can twist the lid with greater ease. The more grip you can get the more grinding you can do, its that simple.
Kozo Grinders feature square shaped teeth that have sharp edges to help break up herb. I’ve mentioned before that I like diamond-shaped teeth similar to those featured on Black Tie Grinders. Diamond teeth do a better job at shredding herb with the least amount of force.
That being said, the teeth on the Kozo Grinder are not bad and will work for most herb fans. For those who are serious herb connoisseurs you may want to find a grinder with diamond shaped teeth.
Other Design Components
Kozo has had a round of updates in an effort to improve upon their original herb grinder. This update primarily includes an increase in the height of the walls on the removable herb collection piece so that the Kozo Grinder can hold more herb.
Kozo Grinders come in a single 2.5 inch diameter size. This is the most common size for personal use herb grinders and should satisfy the vast majority of herb grinder users.
It appears that Kozo varies the price of their herb grinder frequently. I’ve seen the Kozo Grinder priced anywhere from $20 to $24. If you are set on getting a Kozo Grinder and see that it is at the higher end of that range it may be worth waiting a few days before buying to see if the price drops.
Kozo currently only comes in black. Certainly a choice that will work for most, but not exactly exciting. Hopefully in the future Kozo will expand their offerings to include more colors.
The Kozo Grinder is most similar to The Rocket Grinder in terms of quality and styling. Both are fine grinders, but not the best of the best.
Kozo Grinders feel solid in your hands and do have a smooth turning action, which is a big plus. If they’d switch over to diamond shaped teeth this grinder would be really hard to beat.
The vast majority of reviewers have been happy with this grinder, with a select few mentioning that the bottom set of teeth fell out after a few uses. This is a common issue with grinders made from two pieces of aluminum that are glued together.
For those who are unaware the reputation of Amazon’s reviews have taken a beating lately. Some sellers are using unethical tactics to get unwarranted positive reviews. This means you may end up buying something that isn’t what you expect in terms of quality.
We are not going to accuse Kozo of these practices, but their reviews do appear to be too positive for the quality of their product. In fact, reviewmeta.com also finds their reviews to be suspicious.
Does this mean you shouldn’t buy a Kozo Grinder? No, but you should realize that their current rating on Amazon is likely inflated.
Kozo Grinders do not come with many extras. Their grinder box does feature their logo, but is a simple brown cardboard box. Included with your purchase is a pollen scraper which is common with most herb grinders.
What We Like About The Kozo Grinder
- Updated design allows for the grinder to hold more herb
- Priced fairly reasonably and similar to the competition
- Has indentations for your fingers which enhance grip
What We Don’t Like About The Kozo Grinder
- Square teeth are simply inferior to diamond teeth
- Uses two pieces of aluminum which means the bottom set of teeth may fall out over time
With so many herb grinders that look damn near identical to one another it is refreshing to see a company like After Grow take design seriously. Their Thorinder Grinder offers a unique take on grinder design and makes it stand out from all the other weed grinders for sale today.
After Grow has a website that is as unique as their grinder. Check it out if you want to do additional research apart from this review.
With the unique branding around Thorinder it is surprising how little social media is being done around this product. Searching Youtube there are only a few decent videos reviewing the Thorinder, and to date they have less than 150 likes on their Facebook Page.
On top of this the Thorinder is not a top selling herb grinder on Amazon. Let’s dig a bit deeper to see if we can find out why this grinder isn’t getting more attention.
Without a doubt one of the most interesting characteristics of the Thorinder Grinder is the hole pattern. Most herb grinders have a hole patterns that are exclusively made up of little circles that allow for the herb to fall to the second chamber.
That is not the case with Thorinder. The first set of holes are actually shaped like lightening bolts, which does give the grinder cool styling and sets it apart from its competitors.
However, from a functional perspective these special design features do little to improve the actual grinding experience. And with an expensive price tag it is important for Thorinder to not only look different but to perform differently from cheaper grinders.
The teeth on the Thorinder are some of the best we’ve seen on any herb grinder. This is where the Thorinder really excels. You can tell that the teeth were design for optimum grinding. The teeth that align the lid are curved with sharp ends similar the curved teeth found on some sharks.
On the second piece of the Thorinder are teeth that are shaped similarly to a comma. What we mean by that is there is one side of the tooth that is sharp while the other side is flat.
Putting these two teeth designs together makes for a beautifully ground herb that is even and ready to smoke.
Other Design Components
There are several design components that are unique to the Thorinder.
First off, the Thorinder has a smooth finish on the outside, which is certainly different from the traction embedded design that most other herb grinders feature to enhance grip. We are not sure why the makers of Thorinder decided to not have traction on their grinder, but for most it will not make a big difference.
As you can see from the pictures, the lid of the Thorinder actually has a clear top so you can actually watch as your herb is ground. Another feature that we don’t feel is necessary, but does make the grinder look cool.
Price is where Thorinder becomes a pretty divisive grinder, and why we believe the Thorinder does not sell well overall.
If you check on Amazon, currently the Thorinder grinder is selling for around $50.
While there are certainly more expensive grinders out there, including Phoenician and Compton, those grinders have several features that stand out from Thorinder. Some of these features include removal screens, being made in the USA, and top notch machining.
Unfortunately, Thorinder is a great looking herb grinder, but just doesn’t have any features that really make it function exceptionally better than a grinder that is $20 cheaper. This is why we would consider looking at some other less expensive options if you are more concerned with the function of your grinder and don’t care as much about styling.
Thorinder does offer some variety in regard to color.
As you can see from the picture to the right the Thorinder comes in five different inside color options including gray, white, orange, blue, and black.
We hope they had a few more colors in the future as we think green and purple would look really great.
Thorinder comes in the standard 2.5 inch diameter size and a “mini” size. For most, the 2.5 inch standard size Thorinder is the way to go as the mini may not hold enough herb to meet the needs of many smokers.
Thorinder grinder does perform well when it comes to the task of grinding herbs. You will get a nice even grind with plenty of kief left over when you use this grinder. We attribute the above average grinding ability of the Thorinder to its unique teeth design.
That said the Thorinder will stick and build up residue over time and will need cleaned on a regular basis. While typical of most grinders, it is bit more noticeable than we’d like for a grinder in the Thorinder’s price range.
One feature from After Grow that we’ve seen from no other weed grinder manufacturers is the ability to buy individual grinder pieces separately. If you go to the parts section of the Thorinder website you can see where you can buy the individual pieces.
This is actually pretty helpful if you happen to break a piece of your Thorinder Grinder and don’t want to spend the money to buy a completely new unit.
Another cool way that Thorinder stands out from the crowd.
After Grow’s Thorinder Grinder has the most impressive gift box we’ve ever seen for any grinder. It is heavy-duty and presents a good amount of showmanship to the unboxing experience. Check out the video above if you want to see how the gift box opens.
The Thorinder also comes with a top-quality guitar pick scraper that will help you sift through herb and kief.
What We Like About Thorinder
- Very cool design and syling makes the Thorinder stand out from the crowd
- Teeth design is customized and works great when in use
- Gift box is amazingly high quality
- Can buy grinder components separately
What We Don’t Like About Thorinder
- Too expensive for the performance
- May need cleaned more frequently than other grinders
When you really think about an herb grinder, it is different in many ways compared to other weed accessories or tools. In fact, I’d argue that weed grinders most closely resemble a sort of kitchenware. Herb grinders are designed to grind herbs after all!
A brand called SLX Grinders has taken inspiration from other kitchenwares to improve the performance of the standard herb grinder. They’ve done this by using non-stick material ceramic coating over the aluminum four-piece grinder.
As a brand SLX is active in social media and can be found at some industry trade shows promoting the unique benefits provided by their non-stick herb grinders. It is apparent that they are truly committed to their product and making improvements.
With so many grinder brands out there today it is easy to get overwhelmed by all the choices. Thankfully, we will help you take the guess work out when it comes to SLX Grinders so you’ll have the information you need to make a well researched purchase.
As mentioned previously, what really sets SLX Grinders apart from the competition is the ceramic non-stick coating that is meant to help prevent herb from sticking to the wall of the grinder, making it more difficult to turn the lid.
What we really like about this non-stick coating is that it does not include any potential toxic substances like teflon or PTFE. There are so many potentially dangerous materials that are secretly found in your cooking and smoking accessories (FYI, the dangers of using aluminum grinders is a myth) it is nice that there is peace of mind when using an SLX Grinder.
On a more disappointing note, the non-stick coating does not work as well as we’d hoped. Not only did we notice this, but other users also have commented that the non-stick coating does not work as advertised. We hope that SLX continues to improve the coating so that in the future it works better.
At the end of the day you may not be completely satisfied if the main reason you are buying an SLX Grinder is for the non-stick coating.
The SLX Grinder has more teeth than any other grinder we’ve reviewed relative to its size. The grinder has a diameter of 2.4 inches and features an amazing 55 teeth! To compare, the top rated 2.5 inch Black Tie Grinder has 50 teeth, which is great on its own, but not up to par with the SLX.
Personally, we don’t love the shape of the teeth on the SLX. They have more of a square shape with sharp edges on one end. Through our testing at BestGrinder we’ve found that diamond shaped teeth tend to perform best at shredding herb.
Other Design Components
Looking a bit closer you will see that the rest of the components found on the SLX Grinder are consistent with other top of the line grinders.
SLX Grinders come with neodymium magnets that work to keep the lid on while grinding herb so that there are no spills.
The aluminum used in SLX Grinders is aircraft grade and made to last a lifetime.
Lastly, the micron screen is the perfect gage to maximize kief production. Not only that but the screen is simply placed in the grinder without having to be screwed in, making the SLX 20% shorter than standard four-piece grinders, which enhances portability.
It is safe to say the features and design of the SLX are in the upper echelon of herb grinders. Due to this you should not be overly surprised that the SLX costs a pretty penny.
In fact, the SLX Grinder is one of the more expensive grinders we’ve ever reviewed, with the home-size coming in at a price point of around $60.
Even with the unique features, it is hard to justify spending this much on the SLX. Outside of the non-stick coating, most of the other features can be found on grinders that run $30. Given that the non-stick coating has not yet been mastered by SLX, it may be worth considering other cheaper options that do not have the non-stick feature.
This isn’t to say that the SLX is a bad grinder by any means. On the contrary, the SLX is a great grinder. It just isn’t the best value.
If you like color and size variety in your herb grinder, then SLX has you covered.
Size-wise, the SLX comes in two versions: the smaller pocket-size (2 inch diameter) and home-size (2.5 inch diameter). If you plan to take this on the road and grind small amounts of herb then consider the pocket. Otherwise, we’d go with the larger home-size as it is still not huge.
If you are like us, you like your world to be a bit more colorful. Having fun colors in your life perks you up and gets you excited for the possibilities of the day.
SLX Grinders must share this mindset as well as they offer their grinders in many different colors. Currently, SLX sells their grinders in the following colors: silver, gray, yellow, purple, green, black, and gold. With all these color options you can get the perfect SLX that fits your personality.
The SLX Grinder performs very well save for the non-stick coating. It is not to say the non-stick doesn’t work, but it just is not significantly better than other grinders.
However, when it comes to grinding herb and collecting kief the SLX is the real deal. The 55 teeth make shredding a breeze, with the finished product being an evenly ground herb.
SLX states on their website that if your grinder is damaged or breaks during normal use that they will send you a replacement part at their discretion.
Note that it would be wise for you to take a look at their replacement policy because SLX is fairly specific about which resellers are considered legit. If you buy from someone outside of these resellers or SLX, then SLX clearly states they will not honor any replacement claims.
The SLX does not come with a ton of extras.
You do get the typical scraper to help you sift through kief. However, you won’t find a carry bag or any fancy gift box with this grinder. Hopefully, they’ll add these in the future as most other grinders at this price point do offer some pretty neat extras.
What We Like About SLX
- Non-stick ceramic coating contains no toxic chemicals or ingredients
- SLX Grinders come in many different sizes and colors
- 55 teeth is the most we’ve seen on a standard size grinder
- Grinder components are good quality
What We Don’t Like About SLX
- Non-stick coating doesn’t work all that well
- SLX Grinders are expensive
- No extras come with SLX Grinders
The Final Grind
SLX is built on a great concept of developing an herb grinder that is non-stick. As you know many herb grinders get gunk built up over time making them difficult to use and require frequent cleaning.
Unfortunately, SLX has not mastered the technology to create a non-stick herb grinder and what is left is a very overpriced average herb grinder that does not have anything particularly special going for it.
Probably the most important factor to consider once you’ve got the perfect herb grinder is to figure out how to make it last as long as possible. The key to keeping an herb grinder in tip top shape really comes down to regular cleanings.
If you use your grinder on a regular basis like we do, then you know that over time kief and residue can gunk up your grinder in its teeth and grooves. Getting this material off your grinder will get it back to running like new.
With the rise of Amazon and online shopping, new grinder brand have arisen that sell exclusively online. Platinum Grinders is one of these brands that you won’t find in stores, but are available for sale on Amazon.
Due to cutting out the retail middle man, grinders are now cheaper than ever as the brands can sell directly to consumers.
Platinum Grinders takes full advantage of this by being one of the most affordable grinder brands on the market today. And overall their grinders are of decent quality. You won’t be getting any extras with a Platinum Grinder and they do come up a bit short compared to higher priced Black Tie and Space Case Grinders, but that doesn’t mean they are a bad option for those who are short on cash.
The price point and quality balance make the Platinum Grinder very appealing to many folks looking for a quality grinder on the cheap. At the time of this writing you can pick up a 2.5″ Platinum Grinder for only $17.
Most similarly sized grinder will cost you at least $20 a pop. If you want a USA made 2.5″ grinder then you should expect to pay over $50. With that in mind it shouldn’t be a surprise that Platinum Grinder is the best selling good quality grinder brand on Amazon.
There is nothing all that exciting about the design of the Platinum Grinder. It has the standard four piece design and the outside is made from anodized aluminum. The inside is made of another piece of silver aluminum material, which is of lower quality compared to higher priced grinders that are made from a single piece of aluminum.
As with other four piece aluminum grinders, the Platinum Grinder has two pieces with diamond shaped teeth, a second compartment for the ground herb to reside, and then a filtering screen and pollen catcher compartment for kief.
Platinum Grinders only come in one size and color. If you are looking for a specific color or size of a grinder without spending a ton of money we recommend looking into Cali Crusher Grinders.
Platinum Grinders perform well considering there are two separate pieces of aluminum that make up the grinder. The herb is ground up finely by this piece.
However, we are concern about the long-term durability of this grinder due to the two pieces of aluminum that are glued together. Because of this we recommend spending $10 and getting a superior Black Tie Grinder that is made up of a single piece of aluminum.
A strength of Platinum Grinders is that they come with a lifetime warranty. So, if your Platinum Grinder breaks over time during normal use then you can replace it for a new one for free!
It should come as no surprise that as a value grinder the Platinum Grinder does not come with an extras. You will not find any extra scrapper, custom design box, or carry pouch. Platinum Grinders are best for those who simply want a decent grinder and are looking to save some money.
The Final Grind
Platinum Grinder is one of the best selling herb grinders on the Amazon marketplace. From our testing we suggest that the main reason for this is the Platinum Grinder’s affordable price.
In terms of quality, the Platinum Grinder is good, but certainly not up to par with the best herb grinders. If looking for the best grinders in terms of performance look closer at Space Case, Phoenician, and Black Tie.
For those wanting a decent grinder at a really great price then Platinum Grinders are a solid choice.
If you are a fan of the urban feel of the streets and gangsta rap, then Compton Grinders may just be the herb grinder brand for your taste.
These are premium made in the USA grinders that come in many colors and sizes.
Compton grinders also come in many size and piece options from 2-piece grinder all the way up to the standard 4-piece three chamber grinders. They also have features that are exclusive to Compton Grinders that help set them apart from other grinder companies. Let’s take a look at what makes Compton Grinders unique.
As with almost all premium herb grinder brands, Compton Grinders are made from anodized aluminum that helps to prevent scratches and chipping. Anodizing is different from painting so you don’t have to worry about paint chips finding their way into your herb.
The metal screens that are on the Compton Grinder are made of steel mesh and do a nice job of filtering the best pieces of kief into the kief chamber.
Most of the Compton Grinders come in a small or medium size. The small version of the Compton Grinders have a diameter of 2 inches. A grinder this size is best used for light smokers and for smaller amounts of bud. Medium size Compton Grinders have a diameter of 2.5 inches, which is a more standard size found with many other grinders.
Overall, the materials used on Compton Grinders are high quality and potential customers should feel confident in what they are buying.
Compton Grinders have really three features that help them stand out from other herb grinders. The first is that Compton Grinders have a nice ergonomic design that allow users to easily grip the grinder without worrying about slippage.
The second cool feature is the removable screen. Compton Grinders have a small tool that comes with the grinder that allows you to loosen and take out the screen for either cleaning or replacement. We like the design of this as it allows you to tighten the screen so that it is not at risk of falling out.
Lastly, Compton Grinders has a “loading dock” where there are no teeth on a section of the second piece so that you can place your bud without having to break it down to fit between the teeth. This is a unique feature to Compton Grinders and something we feel is a very functional improvement from other grinders out there.
As we mentioned at the top of this article, Compton Grinders come in two main sizes, small and medium. However, that is only the tip of the iceberg when it comes to the variety you can find with Compton Grinders. Compton Grinders come in many different colors. Basically, every color of the rainbow is available for purchase.
With a name like Compton Grinders, you can be sure these grinders have edge, but they also back it up with quality performance as well. The removable screen is a nice touch. The actual grinding action on these grinders is smooth and precise, leaving a quality filtered product left for you to smoke.
According to the Compton Grinder website, they have a fairly weak warranty and return policy. When you compare this warranty to those found from Golden Gate and Black Tie, it just doesn’t hold water. For Compton Grinders you have 30 days to return the product. However, they do not accept returns from a defective item if it has been used, which would make up the majority of return claims.
We don’t feel that this means that Compton has a bad product that they don’t feel confident in, it just seems a bit too restrictive.
Compton Grinders come with a hefty price tag. Usually, there medium sized grinder costs somewhere between $60 and $75. Most of this extra cost is from the Made in the USA factor. If this is something you value highly then by all means Compton is a great grinder. But if you don’t mind your grinder being made overseas there are other great grinders that are more reasonably priced.
With so many grinder brands out there it can be hard to know which is right for your herb. At BestGrinder.net we help you see through the haze to find that perfect grinder at the perfect price. Today, we take a closer look at Kannastor Grinders.
Kannastor sells a large number of different grinders that vary in shape, size, and number of chambers. This means that if you decide to buy a Kannastor you’ll have your pick when it comes to the options to you desire in a grinder.
Kannastor has been making their multi-chamber grinders since 2003, so they’ve had time to work out any bugs in the manufacturing process. This experience is priceless when it comes to proper machining techniques and design improvements.
As with most of the brand name grinders Kannastor Grinders are made from anodized aluminum that is aerospace grade. Basically, this thing is tough, but not any tougher than other quality aluminum grinders out there.
The screens again are similar to other grinders out there in that they are made from stainless steel, which protects the screen from rusting. Gaps in the screen are properly sized so that only the perfect ultra filtered kief makes it to the bottom.
Their main grinder is a 2.5″ four-piece, similar to the standard aluminum grinders out there. However, they also have the GR8TR grinder line that is a full eight-piece grinder that has interchangeable screens and grinder plates.
In regard to materials, Kannastor is in line with other high quality aluminum grinder brands.
Kannastor takes their grinder designs very seriously, which shines through in their GR8TR line of herb grinders. As we mentioned previously, these grinders have eight distinct pieces. Not only are the screens removable on these grinders, but also the grinder plates can be changed out to give you the grinder you desire. There is a screw in mechanism that allows you to flip from a finer grinder to a more course grind. This is the only grinder we’ve seen that has this capability.
All of the multi-chamber Kannastor have easy to remove screens, which can be purchased on the Kannastor website. This helps your grinder last longer without needing to purchase a whole new unit.
Kannastor sells a wide variety of grinders including their GR8TR grinder line, four-piece grinders, and single chamber two-piece grinders. Overall, we are really impressed with the variety of grinders they offer.
Kannastor grinders perform very well overall. They grind up your herb in a optimal consistency that is fine but not so fine that it burns out your herb too quickly. However, other name brand aluminum grinders also offer a grind that is as quality as the Kannastor. So, in this way Kannastor is not alone. However, we must say that the two grind settings on the GR8TR grinder is certainly a useful and innovate feature that had to take some serious R&D to develop.
Kannastor offers a limited lifetime warranty on all their grinders. This even includes malfunction that results from normal use. If you have a warranty claim be prepared to show photographic proof and an order number to confirm your purchase and the issue at hand.
Many of the Kannastor grinder are pretty standard designed and easy to operate with the removable screen being the most unique feature.
However, when you start looking closer at the GR8TR grinder, it becomes evident that this is a complex piece of equipment. We feel that for most people just wanting a grinder to grind your herb with proper consistency, the GR8TR grinder might be a bit of overkill.
If you find yourself in the “I’m just looking for a grinder to get the job done well” camp, we would opt for a standard four-piece grinder from Kannastor and pass on the GR8TR.
The Final Grind
It is easy to see that Kannastor focuses on producing great grinders with features not seen on other herb grinders.
The extra spending they do on R&D pays off with an improved pollen filter and removable screen.
On the downside, they have produced a complicated grinder with many parts and is slightly more expensive than other grinders that at the end of the day perform just as well.
