I appreciate it when people put a little bit of thought and design into simple items. These doors stops from Josh Owen fit that bill perfectly. The "U" shape makes it convenient to hang them on the door knob when not in use, and the silicone makes sure that when you put them on the ground they won't be sliding around. Available in packs of three with a black, gray and green doorstop in each,the $20 price is a more than what you would pay for a wooden wedge. I'd still be tempted to buy a set though, that is if I ever actually needed a door stop.
