We use this tumbler almost every day. It works great, but it runs very fast so you don_ want to leave a wire wrapped cabochon in it too long or it will beat the shine right off the stone. The slow speed is fast. Also, it came with 2 nylon type belts, both which have broken in a short time. We have found some black rubber O rings locally that seem to be working good so far. As for the leaking issue that some complain about...just make sure the lid is seated evenly on the barrel before locking it down .
