So I bought a new microwave for the church kitchen last weekend, as you do. I'm still not sure whether the old one was indeed "broken" or just "too complicated for ordinary mortals to operate", but if I can't make the thing blast some food on full power, then it's got to go.

This is the right way to do microwave controls, especially in a shared kitchen:


Two knobs are all you need

The wrong way is anything involving lots of buttons and confusing choices about what sort of food it is.
