Review: 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.
Review: Fab - Perfect for my 11 year old lad who loves rocks
