Product review (4 stars): Perfect solution to operate without physical switch.
Haven't time tested yet, but this is a savior from our perspective - I didn't want to hack a surface mount switch into a fine Italian marble top... instead this magnetic switch fits onto an insinkerator Badger (and probably other makes too).

Installation and wiring is a sinch if you are "handy".

I've been reading the commentary about the switch not working down the road, but our limited space meant the only disposal that would fit was the small insinkerator badger and this magnetic switch was the only solution I could find on the net to avoid drilling more holes in the surface.

I'm figuring, we are not heavy users of the disposal and that if the whole thing makes two years the dollars invested will work for us... only time will tell..
