Review on 🌑 Removable Total Blackout Window Film | Privacy Window Static Cling with 100% UV Light Blocking | Black Glass Sticker for Kids Room | Day Sleep & Baby Nap Security | Size: 17.7x78.7 inches by Jennifer Wilson

Background: Use this along the top of my drivers side window (I have a low visor so the visor is usually useless); also used to create a dark space (the school uses super bright white stadium lighting at night). Adhesion: Use water or soapy water as directed. Once you put the vinyl on it stays there. If the edges lift, simply wet the area and press back down. Reusable use. Visibility: Ever since I banged it on my bedroom window, it's turned gloriously pitch black. Daylight doesn't wake me from sleep. There are no spooky shadows or cutouts at night. Black. Black. Black. I like it. Warning: DO NOT use if your window is double glazed. The gas between the two panes will overheat and shatter the window. Do not engage in risky behavior. Try blackout curtains. When I use them in my car they do the job perfectly. My face no longer burns. I don't have to lean on the passenger side when the sun wants to melt my face. Doesn't block your view like a wide-brimmed hat.
