Product review (3 stars): Stops disposal splashes well, but don't pour near-boiling onto it
It worked great in every way the first year, especially near the beginning. After that, however, the tips of the rubber splash guard would curl up due to pouring very hot water down the drain (e.g., draining the pasta pot into the sink) . After about the 1-1/2-year mark food would catch on the curled tips of rubber. I cut off 1/2 inch of each tip so food would rinse into the disposal. At the 2-year mark, it's jamming up again due to continued curling. Water splashes out of the disposal pretty bad while it's running, sometimes hitting me in the face. Time for a replacement.
