LG LMV1680ST 1000 Watts Microwave Oven

Pros: It has plenty of power
Cons: Tinny, cheap door.
Constant loud buzzing.

A bottle of Schweppes tonic exploded in a cabinet above our previous microwave. The oven was ruined. Since I was working, my husband did the shopping for a new microwave. He bought an LG, which I hate.
My two major issues are: a tinny door that makes a loud, rattletrap sound on closing. Opening the door isn't smooth either.

When a cooking process is complete, the buzzer buzzes seven times. After a few seconds, if the door is not opened or the Stop button pushed, it buzzes again and again. I'm a busy cook. I know when something is in the microwave, and I don't want to be disturbed by an alpha buzzer telling me what to do. However, one either does something to stop the buzzing or the buzzer keeps on with its annoying sound.

The oven has plenty of power. It has options that I find unnecessary. I'm stuck with this stupid thing screwed to my kitchen wall.
