And given that restriction, I think that these have worked reasonably well.
And since I needed to move the cable at one point, I've also taken a few off the wall, and I had no problems in doing so; no paint came off, and you can't tell that anything was stuck to the wall before.
So, if you can't put holes in your wall, these seem to work well.However, given that you have to stick each hook to the wall and wait an hour before you can use it, it's _way_ more of a pain to use these hooks than the normal ones that use nails.
They _do_ avoid needing to put holes in the wall, but IMHO, that's their only advantage.So, if you can use the more standard hooks that you nail to the wall, I'd stick to the those over using these.
But if you can't put holes in the wall for whatever reason, then these are the best alternative that I'm aware of.
Just a few minutes after I ran the cable, many of them fell out.
I used them to hang up a string of fairy lights that doesn't weigh much at all, so I'm not sure why a few of them stuck to the wall while the others just fell.
The plastic arms broke that hold the cords in place.
I bought many Command products to use once I paint walls but removing clips is hard and they take off a layer of the dry wall when you remove them.
The cord clips without a moveable arm, while a little bigger than I need, are much more durable for cords that need to be moved.
