Is Peel & Stick 3D Wall Systems Really Work?

Is peel & stick 3d wall systems work? well, it is a really an open question, somebody argue that peel & stick 3d wall systems is very easy to install, you just need to measure and place, and you will get a room done is very short time; while others argue that peel & stick 3d wall systems are not useful at all, for it is difficult to get it stick on the wall permanently, after a long period, the 3d wall systems will fall off and it can't be stick again. For me, it depends on the wall you are going to apply to, if the wall is very flat and dry all the days, then the peel & stick installation way may work; but if the wall is stubborn or the environment is web, then we don't recommend to install in that way.
