Dan and John, you're making me nervous. My current home has a GE OTR microwave. I don't trust it, I don't like having my face a foot away from it when it's operating at the same time I'm using the cook top so I stay away from it, it's super annoying to have to open the door in order to get a look at contents of a pot on the back burner, and most of all, I'm holding my breath until it fails.
We bought another Panasonic inverter microwave when we moved (2008) and left the 1980 one behind. It had a smooth touchpad, which I don't like, but it also had a round knob you could simply turn to set the time and push "Start." The thing I liked most was the "Sensor Reheat" option. One touch and it knew what to do. The GE requires scrolling and selecting a few times before it will do anything, so I end up using the "Add 30 Seconds" button a lot.
The Panasonic went to a friend when we moved again in 2018 and is working fine in her kitchen. I had the opportunity to use it on during the 2021 holiday season and I realized just how much I miss it. My only complaint is that the selections I used most wore off even before we gave it away.
