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.

Passion-fueled and high quality
This grit and polish set is exceptional. You can tell it was crafted by people who genuinely care — not just about rocks, but about the process and purpose. This company emanates expertise and enthusiasm, and that shows in the results. My rocks came out more beautiful than ever and I would prefer to buy only from these rock guys. The picture is of some rocks from my apartment landscaping after the process . The instructions are detailed but easy to follow. It’s not your typical instruction manual, rather a sincere document created by the seller from the heart (their tips and tricks included!). It’s really unique and special. I’ve been using a “gimmicky” tumbler set for my HS STEM program and at home with my kids. As a teacher, is a great tool for many lessons and even many subjects.
