Product review (5 stars): Great Play Thing
We left town for a day and arrived home to find this thing missing from the sink - yes - completely gone.  Searched high and low, but never found it.  This was a brand new house - we'd only lived in it a couple of weeks.  We couldn't imagine that someone would break into our house and steal the disposal collar.  Nothing else was missing.  So we ordered the replacement from Amazon.  Couple of weeks later, we finally found the darned thing - hidden behind some floor length drapes in the living room.  A couple of weeks later, we found the collar on the kitchen floor.  This was weird.  My wife finally discovered that our cat whose brain is smaller than a BB, figured out a way to get this thing out of the sink, and used it as her personal play thing.  Oy.

The good news is - the replacement is perfect, and now we have a spare that we let the cat play with!
