Query: total waste of space

I bought this in the hopes that it would save me from replacing a 15 year old microwave and still give me evenly heated food. Wrong! If your food is in a glass bowl or has a high water content, forget about this thing actually turning. Even when it does turn, it only goes for about 30 seconds. You'd be better off putting the money towards a microwave with a built-in turntable.
