Product review (3 stars): Not entirely satified with this product
This item would work much better for me if it were longer.  The throat of my disposal is too long to be able to push food down the splashguard without the stopper stopping up the sink.  However, since I didn't have a stopper for the disposal side, I am glad to have a stopper that works and holds water in that side of the sink when I need it.  So, I guess I'd have to say that it "halfway" works for me.
