Product review (2 stars): It worked great - for a while
We installed the Fiber Optic unit in our vacation home in May of 2012.  October of 2013 - walking into the house after not being there for a month - the garbage disposal is running by itself.  After ensuring the fiber cable had not pulled loose and was still tight into the button, I just unplugged the unit.  After plugging it back in later, it seemed OK, but then 12 hours later it just kicked on by itself again while we were watching TV.  After talking to Waste King, they recommended trying to replace the switch - which I did for $32.  It was OK after replacing the switch for almost a day when it just turned itself on again.  They now recommend replacing my base unit, not under warranty any longer, of course, for another $90.  If I was sure this one would be any better, I would do it in a heartbeat before I burn up my garbage disposal.  Wish I would have installed the Air Switch instead - half the price and the last two houses I have had used them with zero problems.  Now to install one, I need to drill a larger hole in the granite, which is not an easy job for your typical homeowner.  I don't just happen to have a 1 3/8" diamond hole saw sitting in my toolbox.

Great idea on the switch - love the look and the concept - loved the switch while it worked right, but this seems to be a common problem, based on some of the other reviews on here after a year or two of owning.  Twice the cost to buy initially and even more if you have to replace the Base Unit every couple of years.
