I love this grinder! It grinds my bud up perfectly and the fact that you can transform it from it's biggest form to just a simple grinder is awesome. The see thru section shows you how much bud you've grinded so you don't have to keep opening it to check, which is convenient. The overall build quality is great to. It doesn't feel cheap in your hands and it's very stylish and sleek. The packaging is also pretty dope too....a sign of a good company is one that pays attention to the packaging. I would recommend this to anyone that wants a good reliable grinder with a lot of options.....get yourself a Kannaster!

I wish there was an alternate insert so the hold weren’t so large. Some of my nugs slip right through and are still too large. I smoke out of the graviton water bong 99% of the time so the finer the grind the better. Just my two cents; I understand it’s not a product you made. Thanks!

Great grinder for the price

Got very squeaky within the first week but other than that it's okay.
