I have limited shelf space and bought a ge microwave 11 years ago.  That one broke recently when a guest thought he was using the timer but had turned the empty mw oven on instead.  I bought this unit which I think is the 2020 version of my old one. Works great. Operates better than the old one.   Both units move around when you Depress the door open button.  We screwed a 1” X 1” wood strip to the shelf behind the microwave and it doesn’t budge now.
