I really don't care about the popcorn. I'm here to critique your microwave. Your button sounds are good, the door open and close are good, and the beep at the end was good. However, I'm not very pleased with the humming. It sounds like the background humming was interfering with the microwave humming. Overall 6/10. But if the background wasn't there it maybe would be a 8/10 but I can't be to sure as I couldn't hear the humming to the fullest extent.
