Well thought out design. Controls are intuitive. Seems to be plenty large enough. It replaced a Kenmore Elite Convection Microwave we loved, that died (10 yrs old). Easy to install. Really only had to drill 2 new holes into the new mounting bracket.  It used all the existing holes from the old microwave (wow - who would have figured that).  Hopefully we'll get 10 years out of this new one.  It was less than 1/2 the cost of the old one.
