What features do you like in a microwave oven?
What brand has the set of features you like?
For example this one has different power levels but it's awkward to use. It has a way to enter the kind of food it is and how much it weighs to calculate how long it should cook, but I don't know how much it weighs and I don't remember the list of kinds of food, so that's useless for me.
I hate shopping because one has to compromise and you don't know whether you'll like it until after you have it. In the past, they have all been free, starting with Radarrange** Model #2 about 44 years ago, so I didn't have to shop.
**It had a spring broken at the end, so the door didn't work right, so someone gave it to me. 30-minute repair.Mine sparked last night, then collapsed and died. The memorial service is tomorrow, and I have to buy a new one.
