## Customer Reviews

### ⭐⭐⭐⭐⭐ Great item
*by T***N on August 11, 2025*

Works well if you follow the steps...

### ⭐⭐⭐⭐⭐ They are rugged
*by E***D on October 20, 2024*

I really didn’t know what to expect when I ordered these. The ones that came with the rock tumbler didn’t last 24 hours each. These are lasting 2 weeks. I will continue to use these for my tumbler

### ⭐⭐⭐⭐ Works on other tumblers, perfect fit
*by M***. on September 27, 2024*

The media could not be loaded. I have a no-name rock tumbler with no company website. Not a junker, but not high dollar either. Its belts, when broken, are 8 7/8” long. So if your current belts are between 8 3/4” and 9” (possibly even 8 1/2”) these will work fine. No slip, good grip, and the one I’ve put on it has lasted 9 days so far (a record).
