I had a really hard time applying this film. I put it up in my home gym window so that the landscapers and pool cleaners could not see me working out. It looks lumpy and stupid and I spent nearly two hours measuring, marking, cutting, and finally applying this stuff. I followed the instructions and it looks like an old car with bubbled tinted windows. I gave it 3 stars because it does provide privacy but the look is not cute. If your window faces the road, it will kill your curb appeal.
