Don't stick very well, they are constantly falling off and I'm having to replace or stop the dog from eating them.

Does not stick to ceiling well. Falls off too easily.

Really cheap.  They will not stay fixed with the suction cup at all.  Had to lay them down in the freezer and fridge, and then they keep getting moved around.

These stickers keep falling off of the wall, They are really cute and look good on the wall, but it is a constant battle to keep them on the wall

Don't stick to the wall. Keep falling off. I'm so disappointed. I was excited to get them and now wish I hadn't!

They look very cool but they don't stick to the wall well. A couple of them keep falling off.

they don't stay put. We tried this brand three times (stupid us, I know) and applied them according to the instructions, very carefully. One by one they peel off (and dangerously, might I add. I slipped on them a couple of times) in the first couple of weeks.

cheap with sticky holders that lose their stickiness too easily

They sometimes fall off. What I had to do was put a drop of glue to make sure they stay in place. After that they worked perfectly.

I used these put on the back of some wooden clips to use as wall magnets (for pictures). And the adhesive just isn't very strong. They keep falling off.

They work well, but the sticky pads on the back don't stay stuck and they keep falling off of the wall.

These worked okay, they keep falling off the keys and break very easily.

They don't stay on bottom corners with the stickies provided. Would be good I suppose if you use super glue.
