I'm having the same problem as other reviewers (YES, i used the holder). The doublesided tape on this item isn't strong enough to hold the item in place. But, I've also tried a lot of different double sided things to get it to stay in place...no luck. Would actually be fairly nice for a temporary solution to the hot sun heating up my house if it didn't fall down every day. Also, the more you have to handle it, the more the paper gets out of shape so it's a vicious circle. Giving two stars because when it's in place, it looks relatively decent and does the job of reducing the hot sunlight.
