Report "The disposal makes a terrible noise like it has glass in it when I turn it on. The table and blades move freely, food is chopped and washed away properly. One of the "screws" attaching the blades appears to be looser than the other. It kind of wiggles when I put my hand down there whereas the screw attaching the other blade does not move at all. I've run food down it and it seems to be working properly. I've pushed the reset button, and I've tried to tighten the one screw with my fingers. It still sounds loud when I turn it on"
