Product review (3 stars): It's OK - Can be trimmed to improve drainage
We purchased this to use with our Waste King 8000.  It's ok - It's a tight fit and it does drain SLOWLY due to the size of the center hole.  I simply cut about an 1/8 of an inch off of the tips of the flaps to allow for better drainage. Works ok, although I'm thinking it's worth more around $3 rather than the $6.30 we paid for it.
