First one failed after a couple years...locked up. Second one lasted a couple years longer...only to leak all over the bottom of the cabinet and onto the floor. If you have wood floors this can be a disaster. Did some research and found this is a common problem with several InSinkErators. The corrode, the housings crack. Ours leaked right through the center...out the cord opening. Before we noticed a leak we noticed the disposal always stank. I suspect it was because filthy ground matter leaked into an area where it wasn't getting washed away with a rinse. We had been bleaching it...but had to do that often. No more InSinkErators for us.
