When 3M asked me to try these out it was the holiday season and I was excited to try these instead of the clips I normally use. But, I didn't receive these until February. And since I needed to review them, I needed to find something to use them for. What did I find? Power cords! I have a mess behind the entertainment center of cords and cables that have somehow resisted other attempts to organize them. I have hung up 4 so far, following the directions of cleaning with alcohol and pressing and waiting. So far only one didn't want to stay up, so I have have had a 75% success rating. Since I had one fall I am reluctant to remove and replace cords often, like when I unplug and re-plug something in, but it seems to hold things in place pretty well. So if have some left over after the holidays and have some cords getting in your way, these are a great way to clear up the clutter.
