Review on BY.RHO Single Tap Door Stopper - Adjustable Height, Easy Install, Durable, One Touch Style, Two Screw Types - Fits All Floors Surfaces - 4 Inches (Black) by Sarah Cox

I never knew such a thing existed. I loved/hated regular doorstops because when my hands are busy I have to try and hook them with my toe to close the door. I can't do it half the time, and I end up putting down my armful of stuff, leaning forward, and lifting the doorstop. It's much easier to use. A quick press of the little pedal and they pop out instantly. Couldn't be easier. I will never use the old look again. They use a three screw pattern to attach them to the door, which is very common. Makes them a replacement for my old 4 inch doorstops.
