Product review (4 stars): Easy to install and works great
Purchased to work with the InSinkErator Evolution Compact. It installs easily and and works reliably.  My only complaint is the handle design.  It is big and bulky--you turn it over to position it as a drain stopper.  You cannot use the rubber drain strainer that comes with the inSinkErator and at the same time use the control handle.  It's a bit awkward.
