Used to use a microwave with only 3 buttons, start (that performed similarly), defrost, and cancel. The cancel button worked as you expect and the defrost wasn't hard to use. The start button added 30 seconds until it got to 3.5 minutes, then 60 seconds. Easiest thing to use ever. My microwave now has a similar quick start feature of hitting 1-6 for that many minutes and a plus 30 second button. This is how we operate it about 90% of the time.
