I_e changed this to. 5 star rating, as I_e been using this for almost a year now. This is a great tumbler for the price and has exceeded my expectations. I have figured out how to stop it from leaking, it was user error and you have to be really careful. The timer does work. It_ worth the money.I will reserve rating this five stars until I have used this more than 3 times. .....so far, it's a great tumbler. It really does a good job of giving my silver jewelry a high shine in a short time. A couple of things to note.1. The tumbling media that comes with the unit creates a lot of rust. I tumbled the shot alone at least four times and could not get rid of the rust, so I am not using it.2. The top does not seem to close enough to get a good seal and tends to leak a little at times (maybe I'm not doing this right)3. I am not sure what the proper operation is. When i first got this it tumbled in one direction, then paused for a second, and then tumbled in the other direction. After the first use, it began to tumble only in one direction continually. When I used it the third time, it resumed tumbling in two directions....puzzling.4. The timer doesn't seem to work.....All of this being said, I am pretty happy with this tumbler, let's see how long it lasts. So far the results I get with this tumbler are quicker and come out shinier than my magnetic tumblers Lorotone tumbler and the Durabull (horrible tumbler) that I've had in the past.
