Product review (5 stars): MR. Scrappy is PRICED LIKE THE LOW WATTAGE REMOTES and PERFORMS LIKE THE HEAVY DUTY remotes.
We used this to replace two traditional low wattage wireless switches. This works like the low power ones  that are sold in Home D**** & L****, you know the big box stores, except this is designed to handle the wattage needed for a garbage disposal. It is about the same price as the cheap wireless controllers.

My garbage disposal is rated at 1/2 horsepower. In two years I went through two of the cheap ones before switching to Mr. Scrappy.  Mr. scrappy has worked great for two years and actually has made my disposal run faster!  It takes longer to install the remote's battery than it does to install the complete unit.

I am so pleased I added one to control my air compressor which is in my basement from my garage where the compressor hose is located.

Be aware 1) that remotes are designed for items that are built for being always on so Mr. Scrappy controls it all. My compressor has an on off button, so I start the compressor and select the desired pressure from the basement and turn it off from the garage.  In the past I would forget to turn it off and the compressor would start and run for a few minutes several times during the day and night; NOT with Mr. Scrapp. And 2) it like many new items requires a special battery size A23, not expensive just mercury free.

As you can tell I am stocked about Mr. Scrappy!

There are other high power remotes but they cost 4 or 5 times as much as Mr. Scrappy!
