Works great everything you need exeot the rocks and tumbler

Good starter rock tumbler grit. Easy to use and simple instructions. For the price I'm happy with the product. This was my first batch of polished rocks from my rock tumbler the grit worked very well. Recommended

Arrived quickly and produces a quality polish.

The product arrived in a timely manner and all parts of the order were present. Helpful instructions for use were included. I will probably reorder from this same supplier

This looks like a very nice and sturdy unit. They give you several belts for the future. There’s enough grit for one batch. There are four stages that take about one week apiece so it’s nearly a one month long project for a handful of rocks. One issue was where to put the thing. It makes a lot of noise. Plus it walks off the surface or walks around so if you put it on the countertop, eventually it’s going over the edge. I am in stage two and was very impressed with the results of stage one; they give you some pretty square gem cuttings if you want to do those. I chose to do common gravel that I find in my road. I do believe they’re going to be beautiful in the end.

great!
