Unit has very good power.  Installation was very difficult due to odd location of screws in top.  The worst problem is the noise when using the turntable.  A circular plastic piece that goes underneath the turntable is provided for balance, but it does not keep up with the turntable and if you are within 10 feet of the microwave you can hear the plastic piece skidding along.  I can't imagine this was ever tested before it was released.

The unit itself feels cheaply built, but since we've had it for only a short time we've had no problems in that arena.
