Product review (4 stars): Very annoying microwave alarm.
All features work well. Very effective convection oven. Excellent self clean features.  Well written user manual. It took considerable research to find a combo unit with a good microwave as most of them offer only 700 or 900 watt microwave. Actually this was the selling point and the reason I bought this particular brand.

This 1200 watt microwave is especially effective but has a very annoying alarm. For some reason the manufacturer thought it was a good idea to have the beeper go off continually until you open the door. Alot of swearing goes on when we're trying to accomplish something in the kitchen after we know the microwave is finished cooking  and the alarm (which lasts about 5 seconds or so) keeps going off about every 20 seconds. I could understand a short beep every minute or so after the end of the cooking cycle, but not this. You can turn off the alarm, but then you have no sound at all. Not a whole lot of thought or insight went into this ridiculous alarm design.
