Product review (5 stars): Perfect Fit!
Fits perfectly in my sink.  I bought one at a local store which was supposed to be universal and it was much too big.  I bought two of these, and although they are stiff when installed, after a period of time the flaps become more pliable.  The noise level was reduced so much after installation it was unbelievable!  I'll definitely be reordering when I need a new one.
