I was replacing a very old Insinkerator product, so installation was a breeze. My older unit was a cover control model and I replaced with the same. I really like not having to wire a switch to turn it on and off. This new unit is so quiet, it’s hard to tell that it is even running. Highly rated by Consumer Reports as well. If this unit lasts 20 years like the last one, I will be beyond satisfied. Highly recommend to anyone need a new garbage disposer.
