User Experiences
5 Reviews"I purchased this film primarily to reduce the afternoon glare in my home office. Installation was straightforward, though I recommend using a sharp utility knife for the edges. It has significantly lowered the temperature in the room while maintaining a soft, natural light."
"way comfier then the cheap stuff. took a bit to puff up but its good."
"It cleans well but it's kind of awkward to hold since it doesn't have a handle or anything. Good quality material though."
"My 4 year old is obsessed!! It's the first game he can actually play without me helping every 2 seconds because of the auto-drive. Total lifesaver for rainy days."
"idk they are alright i guess. the straps are a bit tight on my ankles but the grip is good."
