Product review (5 stars): Perfect sink stopper for the insinkerator garbage disposal system!
The guy who installed my new sink and garbage disposal lost the stopper that the insinkerator came with....so I went online to find the replacement and came across this product.  It got pretty good reviews so I decided to try it - and I think it's fantastic.  You can leave it in the sink, it will allow water and small food particles through and when you need to run larger food through the garbage disposal, it is easy to pull out, unlike the original stopper which always either turns over and is hard to remove OR it stops any water and food from going down the drain at all.  I'm not sure why other reviewers had a hard time getting it to work as a sink stopper, you simply have to push it down all the way when you want to use as a stopper. This item is also much nicer looking - I highly recommend it, it's totally worth it, you'll be very happy with this product.
