BOught this as a replacement for an older GE model that died after a recent move to a new house. 
Basically this was purchased due to its dimensions as the older unit had matching filler plates on the sides as the cabinets are spaced further apart than the standard width of microwaves. Fortunately the mountain bracket was the same and I didn’t have much to change for the installation making it quick
The microwave has worked well for what we do, reheats, cooking vegetables and some basic things with an occasional defrost. The melt butter feature is ok, but don’t be fooled thinking  it will only soften it. Otherwise a decent product for the price and would buy again
