Product review (1 stars): I would never buy this wireless control switch again.
I bought a Mr Scrappy Wireless Control Switch on 4/16/12 from Wayfair, to go with my new garbage disposal purchased the same date.  The remote control switch stopped working on 2/12/13, and I was advised by Wayfair that there was no warranty.  So be aware that this product is made in China, and you will never know when it will stop working.  I did send a e-mail to the company (Joneca Corporation) to advise them of my problem.
