My WIPPS Mouthgpiece is great...

as a doorstop. It's the perfect thickness to fit snugly under the door in my son's room. However, it doesn't totally block the door so you can shut the door without having to move a giant steel "jack" or a concrete block. I love it!!

I'm glad I got a Gladiator custom or I would have never realized what a wonderful doorstop a WIPPS can be.
