Product review (4 stars): Owned for 7 years
We loved this Frigidaire microwave. And we were heavy users (2-4 times a day).  The beeping is pretty loud and it does make you open the door in the middle of defrosting only to hit start again, but other than those small nuisances, it worked great for us for 7 years until it just plain died.  Our only complaint is that the range hood had a very weak fan with only one setting (on).
