This is a good product IF YOU DO NOT REMOVE THE LINING. DO NOT follow the instructions, just stick it on the back. I tried to do it according to the instructions, but in the end it turned out to be mush. The air bubbles will never come out and it looks awful. The first photo is when I tried to attach it the way you "should" and the second after I bought another one and just glued it to the back. (I also installed a second row of lights from the top to make it look more blue.)
