This disposal replaced one that I installed about 20 years ago of the same brand that still functioned, but the actuator switch was faulty. This disposal was easy to install, and works great and is quieter than the one it replaced. The new on off switch is much easier to use and is magnetic. Now I get to see how much iron is coming through the pipes from the city water. Overall very satisfied and glad I stayed with the Insinkerator brand!
