### ⭐⭐⭐⭐⭐ Kids fun
*by A***R on June 29, 2025*

A little loud with the lid on but great starter kit for kids

### ⭐⭐⭐⭐⭐ Quiet and Impressive Results.
*by T***S on March 9, 2025*

Birthday present for a grand daughter that is impressed by rocks. Quiet and really smooths small stones. This will only work with stones 1.5” and smaller.

### ⭐ Broke after 2 Days.
*by A***R on June 18, 2025*

I am on Day 2 of Phase 1 and my rock tumbler broke. Of course it is 12 days after my return window has closed. I am sad to say I had hope that this would work and now I'm too sad to even look at my favorite rocks that I had placed inside because I'm sure they're ruined.My broke: It is making a loud sound like it's not functioning any longer.
