I highly recommend this product, first it is full of stress to the installation because it is long to do ... that said, we respectfully followed the instructions, (INDICATED at the address specified in the information on the purchase) but despite this, there are still bubbles appeared several days after having placed; I am very disappointed with this, because first, it is expensive for what it is. Finally, the only positive is its power not transparent, but at night, you have to close the shutters because light can be distinguished even when the forms, and in a bedroom, intimate place, n ' is not terrible ... If I had known this, I would have taken the same product that I had several years ago, that has a real static power because of THIS MOVIE FROSTED Xénotec has no static pouivoir; even if he had badly laid, I could understand, but this is not the case, so in my case, I lost 28.50 because I guess I can not return a product to be découipé refunded!
