Review (5/5): Works perfectly
I saw a lot of people complaining that this doesn't stay put, won't stick to a surface that's not completely flat, and can't be remounted if it's taken down. I tested each of these theories and, as you can see in my pic, it stays put even though it's on a ridge.
If you remove or move it you just need to make sure of s few things. When putting it back up, make sure the back of it and the new surface are completely dry. Put it up with nothing in or on it. Leave it in place for a few minutes before you put anything in or on it. I've had mine for over a week and have removed and replaced it 3-4 times with no problem.
It's a great space saver and I love that I can take it with me on trips so I have everything at my fingertips.
