## Customer Reviews

### ⭐⭐⭐⭐⭐ Good grit
*by T***B on August 22, 2025*

This grit worked great for my first ever Columbia river rock polishing experiment. I didn't have enough stage 1 grit from the "starter" pack I originally purchased. I added another 3 TBSP to my tumbler and the rocks look great at stage 1

### ⭐⭐⭐⭐⭐ Best rock tumbling grits on Amazon
*by M***E on May 19, 2025*

I have been rock tumbling for over two years now and I have purchased this brand multiple times and will continue to be a return customer. The grits work exactly as expected for each stage of tumbling. Important notes:- Get the one that has the ceramic filler - not the plastics. The ceramic will last way longer and be better on your rocks.- Also - watch some YouTube videos on how to tumble rocks and switch between stages. There's some important tips to make sure you get the best results. Michigan Rocks YouTube channel has some great instructions on it.For the price and quality, couldn't be happier.

### ⭐⭐⭐⭐⭐ Best stage 4 grit for the $ on Amazon.
*by B***2 on July 14, 2025*

Shines up rocks with ease. If your a rock collecting nut that loves to polish rocks like me, this is some of the best prices and available stage 4 polishing compound on Amazon. Batch after batch, I’ve gotten consistent results from Poly Plastics grits.
