4-Step 3LB Rock Tumbler Grit and Polish Refill Kit, Premium Rock Tumbler Media, Effective Rock Tumbling Supplies for Producing Gorgeous Polished Stones, Suitable for All Rock Polishers and Tumblers

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

The best media I have found for rock tumbling.

Good for a beginner or a person that does a few items.

Have been using for a few polishing cycles, and so far have been impressed with the results. Biggest con is the measuring spoon doesn't fit the lid, which is a huge oversight. Rocks get nearly perfect after following the recommended length and time, we can't wait for more cycles!

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.
