I purchased my first one about six years ago.  It fit the space I had built perfectly.  It lasted about 3.3 years.  I purchased the 2nd one, exactly the same model, it lasted just over two years.  Today I had to buy another Microwave....I will never buy a Frigidaire again.   The old Microwave that was put into the house in 1980 was still working.  I replaced it with my first Frigidaire.   Do not buy a Frigidaire Microwave.
