we purchased the oven to replace a previous model that had microwave issues from the third year forward.  while otherwise pleased with the first model, the second one has a microwave door that opens down, and most people won't be able to reach the back for cleaning without a stepladder.  the oven takes longer to heat than the predecessor.  in retrospect, i should have had the first unit microwave repaired a second time.  also, it didn't install with the spects indicated and required more work and time at that poing.
