I bought this microwave as a replacement of another brand which was brand new but had an issue tripping every GFI circuit in my brand new house, that unit was returned. This unit is wonderful, I love all the pre-programmed sensor cooking selections.  It is the perfect size, not too big that it takes up excessive countertop real estate, but large enough to hold a good size casserole dish.  It heats food fairly evenly and is also attractive on the counter.
