## Customer Reviews

### ⭐⭐⭐⭐⭐ Good product
*by E***Y on 28 May 2025*

On our third week of tumbling rocks now and the results are looking good, comes with good instructions and a sample of grits, as well as some rocks to tumble. Was simple to set up and can hold a good amount of rocks too, a smaller one would probably work better for beginners. It’s a tad noisy so is living in the garage!

### ⭐⭐⭐⭐⭐ Brilliant
*by A***A on 22 January 2025*

Works very well so far as had it on for 4 days to date. I have noticed the device moves forward at speed 3 very gradually overtime so I would keep that in mind if placing on a small table and is left unattended for a long period of time. As expected can be noisy but kept in a spare room you won't notice its on. Very pleased and works wonders on crystals and pottery shards. Looking forward for up coming project's with this device. Also comes with spare belts. Great! Thank you!

### ⭐⭐⭐⭐⭐ Tumbles well wirh adjustable speed
*by J***O on 4 February 2025*

Tumbles well, hope it lasts. Will update after a few more barrel fulls.
