Been wanting to buy one of these and now I finely did, Bought a cheap EBay China built tumbler, The first thing I'm going to try to clean is about $70.00 dollars worth of coins that came out of our burnt house, After that I have all kinds of nuts and bolts and "Small" things I'd like to clean up.
Should be here in a week or so, I'll post a update at a later date.

later,dave

• Tumbler Polisher

tumbler might remove too much metal,might be better to use an ultra sonic cleaner.
