Product review (5 stars): Works great - well designed
I wanted to install a garbage disposer in my new home, but there was no switched outlet or circuit to attach the garbage disposer to - only a regular outlet. I purchased this adapter along with the InSinkErator Evolution Compact disposer (one of a few disposers that fit my limited height requirements) so that I could operate the disposer without having to add a wall switch.

The adapter works well; it comes with a special flange and a special black plastic magnetic drain stopper / control. The only complaint that I would offer is that the black plastic stopper is not as attractive as the stainless steel stoppers that many newer disposers come with, and that you have to push it in rather firmly (and upside down) to stop up the drain completely when you want to fill the sink.

There is a dearth of technical information about the product online. The InSinkErator website doesn't even mention it. It is very easy to install (clips onto the fairly standard quick-mount screws) and just wires between the incoming hot power wire and the hot terminal / wire on the disposer. The adapter comes with a alternative, round backup flange. I used this, but if I ever did an install again, I think I'd try first with the standard triangular backup flange that comes with most disposers. This adapter is listed to work with any Evolution series disposer, but I am 99% sure that it would work with any InSinkErator disposer (including the much cheaper Badger series) as well as many other manufacturers disposers that use the fairly standard three screw quick-mount systems.
