Product review (5 stars): Works awesome!
Simple but very effective part to keep your washer hose from coming out of the drain.  I used this product on a 1 1/2 inch drain pipe and the standard hose outlet that came with my Kenmore washer.  There are no leaks and there is no way the hose is coming out of this thing.  The pictures don't show it real well but the inside is tapered to accommodate different outside diameter hoses.  The tapered design allows the hose to push through firmly.  Once the hose is in its not coming out without a considerable amount of force.  I am very happy with this product.
