Review on Sturdy Classic Rubber Door Stopper Wedge - Stackable Doorstop for Gaps up to 1.2 Inches (4 Pack, Brown) by Michael Boyce

This plug will not stay in place and place on any surface. She slips on wooden floors. She slips on tile floors. She glides on marble floors. She slips on carpets and cloaks. I ordered four packs based on reviews and price so now I have four useless pieces of rubber I can't even hold the door open with. I literally better take a rock from my yard, at least the weight of the rock offers some resistance and keeps the light door open. critical doors as extra protection against burglary, but forget it. Rubber is not only grippy, but also thin. If I put my foot on it and pull on the door, the rubber itself flexes and flexes. It won't withstand any pressure even if it can grab. With all the hide and seek rules, I'm embarrassed to return them so I just toss them in a random garbage can in the garage hoping I'll find a use for them one day.
