Product review (4 stars): Splash Guard works fine
Replacement splash guard for my Waste King disposal has restored functioning to like new, after the old one lost its rigidness and started falling into the disposal.  Unlike another review I had read, no need to glue the new splash guard in.

Only reason for not providing a 5th star is that the sink stopper did not provide a tight fit, but since I didn't need such a replacement this wasn't an issue.
