Product review (5 stars): So happy I found this, fits great and works well.
Man oh man, I have been living without this for years after mine finally fell in to the disposer a few times and got mangled.  I am so happy to finally be able to use both sinks in my kitchen.  This item fits nice and snug in my Montgomery Ward 3/4 HP (made by Tappan) drain.  I am very pleased with the product and purchased and extra spare as well.
