Product review (4 stars): Honey, I shrunk the sink stopper...
This works great, fits great, I was very pleased with it until I put it through the dishwasher.  Totally my fault, but be advised, it shrinks if you put it in the dishwasher.  Also, water wasn't passing through it quite quickly enough so my husband widened the gaps between the flaps for me.  I'm buying another one to replace the one I ruined.
