One Way Window Privacy Film Sun Blocking Mirror Reflective Tint Heat Control Vinyl Anti UV Window Stickers for Home Office

Looks good but haven't used it yet and no instructions came with it on how to fix it to the window pane. Apologies to seller. Mixed up 2 similar rolls I received together. In fact I did have clear instructions how to fix them to window pain and I'm so happy with the result! Work perfectly!

The product is good with simple instructions BUT… removing the plastic sheet from the reflective film is really difficult and I spent more time trying to do that than I did putting in on the windows

It came folded! I still tried to put it on window, guess what! I can't see anything, it's just a black foil! Don't buy it!!!!!!!!

As long as the light in the house is weaker than the light outside it's cool. Otherwise put two layers of black.
