Hobby Rock Tumbler

This is a great product. It takes a very long time to do these rocks though. I hadnt expected that. There are many steps to each batch of rocks. The tumbler runs for multiple weeks all with different grit as you go. It has very good directions and so far it has done a good job on rocks.
