I own this one [1]. Defrosting is manual but otherwise it’s the best microwave I’ve ever owned. I also expect it to last for a long time since it’s a commercial grade. Single dial for time. Single beep when done and NO other sounds. Safe and intuitive enough for my kids (inset in our island cabinet at adult waist height).
