I didn't even clean the surface of the door and it worked great

As long as you follow the directions (cleaning the surfaces, waiting before putting weight on them) the item works wonderfully.

And best of all you can put them up on your cabinets, walls, etc... and they won't mar or ruin any surface

I use these on smooth surfaces such as doors instead of on uneven surfaces such as orange-peel walls.

You simply clean the surface with rubbing alcohol, apply tape to back side of the hooks, then press it on the wall in the desired place, then slide the hook off of the taped assembly to make sure the tape is secure, then slide your hook back on......DONE!

I use these on smooth surfaces such as doors instead of on uneven surfaces such as orange-peel walls.

They are a handy way to provide a hanging surface, without the need to damage a surface with screws or nails.

Easy to apply to clean surfaces.

I followed the directions EXACTLY, and cleaned the surface with rubbing alcohol

I would advise attaching them to an unpainted smooth surface.

As long as you clean the surface and apply pressure to it for a couple min when placing it on wall it will hold forever!

I tried using a surface cleaner and then drying and the first time I installed it, it came down

Would definitely buy again to use on a smooth surface.

This hook is the perfect shape (a nice u-shaped opening) for a curtain rod, whereas some others create a "pocket" that's more of a v-shape or flat shape where curtain rods might not rest as firmly (although they'd probably still hold up well).

Works as you would expect.

Wasn't sure these would work as I needed a robe hook.
