This was a LIFE SAVER!!!!!  My disposal would only hum when turned on.  After inspecting, I didn't see anything that would be causing any issues.  I called a plumbed and was told just to talk through the door would be $100.00!!!  I found this, received it, used it as instructed, and my disposal was working in less than 5 seconds.  Amazing.

This is a lot nicer than just a standard allen wrench because of its size.  It's large enough so you can get a nice grip.
