A Really Interesting Hobby
Very well produced and well packed. Comprehensive kit, with easy to follow instructions, making it easy to use and set up. One thing I didn't realise was it would take so long to produce the finished items. Each stage, there are five, takes several days to run. So don't expect rapid results. It is worth the wait for the drum to stop turning, seeing the magical change in the stones is wonderful. Great piece of kit and glad I bought it. Grandchildren love it.

A useful addition to the rock tumbler, especially for beginners.
Bought as an addition to the rock tumbler so that grandson had plenty to go at. It's a useful addition to prevent you having to seek out replacement supplies.

Satisfying.
Easy to set up. Good selection of stones supplied. After 5 days a good enough finish to delight 7 year old grandson. As warned it is very noisy so better in a garage or she'd.

A professional looking kit.
I bought the rock tumbler from you as a Xmas present for my grandson, looks good, but obviously not used yet. I then purchased the refill pack to give him a good start. I think he will love it.

Very bad bag of stones
This is a bag of dust. Very few stones that will tumble successfully. Will be returning it.

Alles super, so wie vorgestellt! Was mir fehlt ist ein Hinweis, woher ich die Schleifmittel bekommen kann. Hans
