I was a bit worried since a few reviews on here say its see through or it doesn't stick well. Well those reviews are BS. They're either lying or didn't bother to apply it right.

It does require a bit of effort to apply this. They aren't kidding when they say to soak both the window and the film. If you don't, the film will stick to the window like tape. When both are wet the film is easy to adjust and move, or even remove to get a better angle. Once you apply it make sure to use the squeegee they provide to push out any air bubbles. You'll have to do this several times for a couple days. Like I said, good things require a little effort.

It's also completely opaque. I tried looking through it on both sides during the day and night. I couldn't see anything. I even used my 1000 Lumen surefire flashlight to find if any light can get through. The best I could see was just the LED lens of the flashlight with a red tint. Most household lights don't produce 1000 lumens, since its completely blinding. If that's the best I could see then I think I can trust this stuff.

I trust it well enough that I'm currently using it for a large bay window in my bedroom. I don't have any curtains or shades anymore. The only problem is that now I really need to rely on clocks since I can't tell if it's day or night at all.

I'm going to give us only four stars because I think that it would be very helpful if they could mark which is the film and which is the tint to someone like say myself that has never done this before it is kind of confusing I will not lie it was not easy and it didn't slip right off with soapy water! I did a full window so it has two sides has to be redone and unfortunately I'm gonna have to rebuy it because I couldn't figure it out and it's not as easy as they say it is in a nor does it come apart as easy either! I will say thought that it completely blacks out your windows so there is a little anxiety there and it's hard to get used to because you cannot see through it and you cannot look out of it either! Talk about privacy it's like having a black window made out of concrete because you can't look either way! No joke! But for someone like myself who hates the sun and wanted a window that was blacked out it works perfect but like I said maybe in the future you guys can take the time to mark which side of the tape is the back part of the film and which is the tent it would only take a second and it would probably save a customer the hassle and disappointment of ruining it. So for now 1/2 my window is done. It's not cheap so that's why I suggest you guys let the customer know which side is the back and which side is the film.

My husband has to have the bedroom pitch black to sleep. We have tried several things, most of which prevented me from opening the windows during the day for fresh air. We have tried films before that didnt completely black out the light. This WORKS! I am so happy to be able to open the windows during the day and sleep at night.

Talk about turning day into night! I work nights and put these up in two of my windows in the bed room when I was finally just done with any light getting into my room during the day. Instantly day became night and my quality of sleep has improved drastically. At first the tint was a little rough to apply to the windows but once you get your style down the application is much smoother and with allot less bubbles and creaks. Plus, it really isn't that much of an eye sore.

This works wonderfully. For some stupid reason, my apartment has a huge window in the shower. Not a typical window shower that maybe is above your head or at eye level but completely in line with the torso and just below. This is holding strong on that window, providing me with complete privacy. Just make sure some is there to help you install.
