Our 16 year old GE microwave died and we bought this model as replacement. Literally the best thing about this choice was that I was able to hang it using the old mounting bracket right where it was already. Our old unit had a better display, dual wave generators, and a more solid build. Most manufacturers have definitely fallen from the peak where engineering, build quality, performance, and price had converged. 
With that in mind, this unit to me is a reasonable choice as long as you’re not looking to be impressed. Our old GE unit could cook the same items in less time and I remember the feeling that we had a cutting edge unit with a good solid feeling door and the highest technology available at the time. With this one I feel like all these years later we have actually gone backward in those categories. I’m hoping there are design improvements I am unaware of that will help this unit last years longer than the old one, but I am aware that isn’t the goal of manufacturers these days.
