Product review (3 stars): Great quality - doesn't work
After diligently researching for a replacement baffle for my ISE disposer, I thought that I had found the answer in the ISE "QCB-AM Anti-Microbial Quiet Collar Sink Baffle, Black" as described on the amazon.com site.

Unfortunately, neither the description nor the reviews mention that this will not work with a "batch-feed" disposer. That is, one that requires you to use the stopper to activate the unit, rather than use a wall switch. I didn't research diligently enough!

The part fit great and looks that it is very well made so I hope that ISE makes a replacement baffle similar to this one that I can purchase.
