Product review (1 stars): Very Flimsy. Rip-off - do not buy!
Useless. The previous splash guard we had for the "In Sink Erator" Sinkmaster unit has lasted 6-7 years; the rubber was finally breaking down and needed to be replaced.

This one is simply crap. The whole piece is made of thin, soft, and generally flimsy rubber. It uses maybe 1/4 the rubber the old gasket used; the perimeter has just a few narrow ribs and doesn't grip the edge of the disposal well, at all. It is the right size, but the thing is so flimsy it just folds and slips into the disposal whenever I turn the water on.

VERY annoying that I have to pull the thing out of the disposal whenever I want to turn it on - AND I have to carefully aim the water at the center hole, so it doesn't fall back in while the disposal is running.

I even bought a back-up, assuming this would be a quality part based on most older reviews. Yet another case of bait-and-switch, it seems :(.
