Once I attached the two hooks that I originally needed, I found that another hook would be useful to take up the slack of a fan cord. I then realized that there were a few odds'n'ends that these extra hooks could be of use...keeping things off the floor so my ferret wouldn't stash objects away.
Just remember to use the higher weight limit strips/hooks for the hooks that are used frequently...otherwise the strip might tear part of the paint off your wall. Yes they are strong.
Particle board binding is not so good. Too bad...maybe 3M can work on that one.
I am happy to say that I haven't been disappointed in any of the products.
