Query: A Piece of Junk

There seem to be a number of positive reviews for this product, but it sure seems like a piece of junk to me. I have tried two of them and neither would play a record without sticking every 10-15 seconds - either with the included cartridge or a Shure cartridge I had sitting around. One of them came with a warped platter, and the second one would not hold a constant speed - it kept drifting faster and slower. On paper it looks like a nice unit - built-in strobe, a standard interchangeable cartridge mount, etc. As a number of reviewers mention, the unit feels cheap. I could live with that if it actually worked, unfortunately it failed to actually play a record.
