Will buy again

I purchased a rock tumbler, the first time I uses it I used the grit it came with. I wasn't happy with results. So looked into different grit. I only used the shine grit ( last stage) on the rocks that had already been tumbled with a shine grit and I was surprised at the difference. I haven't used the others but I'm sure the quality is just as good.

Worked as advertised

I'm new to rock tumbling, I've used a few different polishing grits and this is the best one so far. I ran this polish cycle for 7 days and am happy with the results.
