Platinum Grinder Review

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.


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!

Lifetime Warranty

Golden Gate Grinders offers a generous money-back guarantee on their grinders so that if anything were to break or not work properly you are not out any money!  We love to see this money-back guarantee because it shows that they believe in their product and are confident that you will love it too.


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.
