Review on Ilyapa Solid Door Stops - 10 Pack of Heavy Duty 2 ⅞ Inch Door Stops - Traditional Design in Black with Rubber Bumper - Ensuring Your Doors Stay Secure by Rachel Marie

The screws that go into the wall to screw the doorstop are very flimsy and pliable which is a terrible combination with the knob being designed for a flathead screwdriver. Even slight tugging on these screws will cause the screwdriver to slip and snap off the screw head, rendering the screw useless (and you only get 1 screw per doorstop). This happens even AFTER you've pre-drilled the screw hole. The screws are just terrible. If I were you I would get a different set of doorstops from a different brand.
