The microwave part works very well, better than any other I've used before. It usually undercuts the preparation times suggested by instructions on food packaging.

All other modes however use a heating element that only covers the back half of the device, relying on the rotating dish to achieve some degree of even distribution. This only works to an extent, the center doesn't get nearly as hot as the outer diameter. The heater also appears to emit a lot of infrared energy, which can heat non-uniform food unevenly.
