Product review (4 stars): Fits perfectly, hole is too small though.
I know I might be voiding some safety issues here, but I found that the flaps were to tight to allow air and debris through properly. I cut every other flap about half way down, and now it flows much easier. I know its like that for safety, but other disposals I have used do not have this issue. As far as the fit, it fits my old disposal perfectly, and the stopper fits where big box "universal fit" ones did not.
