WochiTV Total Blackout Window Film 100% Light Blocking Non Adhesive No Residue Removable Opaque Static Cling Privacy Glass Tint for Home Bedroom Darkening Heat Control (35.4 Inch x 6.56 Feet)

The product works without any adhesive, which is fantastic, cleaning the surface well will help and most importantly: since it comes rolled up, you first need to do some "unrolling" to flatten then sheen, otherwise the sheet will bed away from the glass and end up falling due to gravity. In my case 99% of the sheet adhered to the glass perfectly, and for the flaring edges I aplied a small tape to secure them

Blocks sunlight completely... When installed correctly I have a large window that is hit by sunlight ALL DAY sunrise to sunset. I got more material than I need since you have to cut to size, and I'm glad I did. Even though there is a grid on the film, it did not seem to be square when following it I made 3 attempts to get the right cut, first one was bad (my fault not the product, I used a dull blade to finish the cut in the final step) 2nd attempt was perfect size (you definitely want the slight overlap, it says 3mm extra) I struggled to get the corners to block all light completely because a complete square overlapping on a concaved window means small creases at the very corner 3rd attempt I cut with 5mm excess and with a brand new blade and CAREFULLY made tiny darts at the corners to stop the creasing By this point I've ran out of material for further attempts but this was perfect! Room is in complete darkness even with belting sun shining on it!

Hard to manage, doesn’t help with temperature from the windows, they are good for blackout/privacy

I have tinted a lot of house, windows and a lot of car windows and this has to be one of the hardest window tents I’ve ever tried to use. The backing does not want to come off of it no matter what you do you can use tape you can try to use your fingernails. You can try everything, but it was absolutely Horrible it took me over an hour to do one window just because I was trying to get the backing off of it

Great product for the price. Easy to install and looks amazing. Blocks out 99% of the light. Definitely recommend. Ps. Don’t mind the mess in the reflection remodeling the room on the other side so everything is in the dinning room
