I love this tumbler! I use it with Shine Brite detergent and get fantastic results. I have had the machine for about 9 months and the first time I used it I noticed the pressure of the closure against the acrylic top created a little crack in it. No problem yet, because it doesn't leak. Now, the belt has broken, and looking at it, it is apparent that it is glued together in a few places. It is unique to this machine. I bought a vacuum cleaner belt and had to cut it back a bit to fit properly but it works. I have since been told by the seller that they DO NOT sell the belts, but I can find them on Amazon. I just ordered 5 (about $17 for all) vs the $10 vacuum belt. About 2 months ago there was a rattle inside the machine so we took it apart, and used electrical tape to adhere the motor back into place. I think it is cheaply manufactured, but great for the price. As long as I can keep patching it together.
