Query: Microwave Turntable

This item really doesn't work that well. Whatever you place on top tends to shift position or slip off which causes the turntable stop. This makes it necessary to stop the cooking process, open the microwave, re-adjust, and start it up again. Therefore, you have to keep a constant eye on things. The other thing is, the turntable turns so slowly that at first I thought it wasn't working. I finally realized that it was working, but that it turned at a snail's pace. Overall, I am not at all thrilled with this purchase.
