I love the size and it works well. The functions are full with things I suspect people rarely use. Most people using a microwave just want to open the door and heat something fast. Not press 1 press 0 press 0 press ok. Speed buttons are much more used functions like press 1 and immediately one minute goes on full power. Have been unable to understand the codes for changing the weight to pounds and the manual does not specify. 
We had a great company in Albuquerque NM install our microwave called Smart Homes LLC. Very knowledgeable and handled all the hurdles with the new outlet wiring, new ductwork, and tile work. Smart Homes LLC was really great!
