We got our first over the range Hotpoint Microwave about 20 years ago.  It has worked flawlessly all these years.  And, would still be working except that a guest had put some soup in the microwave to warm it up and inadvertently left a metal spoon in the bowl.   That was it for the microwave, I am sure it would have lasted many more years.  So, for a replacement I bought a new over the range Hotpoint microwave that is almost identical to what we had.  And, it working great just like the old one.
