Bests & Worsts Reviews from Amazon

My 20+ year old tumbler died and I wanted a new one to play with. This one had good reviews and a reasonable price, and it arrived quickly. 10 minutes after unpacking I had it up and running -- easy as pie. It also looks more durable than my old one, although I'm a little worried about the belt. I'm deducting one star because the package had obviously been opened, the contents handled, and then sloppily repacked. It seems to be OK, and all the parts are there as far as I can tell, but it made me nervous that something was wrong with it. I would not have bought a package in the store that looked like this and I am getting seriously tired of buying "new" things from Amazon that have been previously opened.
