I found the idea very amusing and have accessed so. The underside is unfortunately made of smooth hard rubber and holds neither tiles nor on a carpet door. Especially not when the door with backpressure automatically goes through an arm. My own solution: Velcro glued underneath. Thanks to this work, at least on carpet. Unfortunately, the rubber is at the top and too thick, that is hardly a wedge. Thus wedging is hardly possible. I think that is certainly here a joke article that was never designed as a doorstop, but is still sold here under the name. Too bad if the amusing appearance.
