I'm sorry to disagree with all the positive reviewers, but these were a disappointment. Maybe mine were manufactured on a day that the sticky-stuff machine was broken. These little things want to do a good job, but they just didn't stick. Not only will the sticky stuff fail if you yank on the cord, they also fail without any provocation whatsoever. I stuck one on the desk near my computer, and when I came back into the room less than 12 hours later it had lifted off the surface. The cable was keeping the clip from falling on the floor, not the other way around. These clips are mocking me; I just know it!
