Total Blackout Window Film: 100% Light Blocking, Room Darkening Static Cling - No Residue Film for Privacy, Home Security, and Day Sleep - Easy Removal UV Prevention Treatment (17.5 x 160 inches)

This is for the blackout version. It works great, it is completely opaque. This might sound obvious, but this is not easy to find, as a shift worker, I have tried many "blackout" products that let a lot of light in.I actually found this to be a pretty forgiving DIY project. I'm not particularly good at anything that requires steady hands or fine motor skills, but these sheets stretch and are easy to cut. I even dropped a piece a couple times, but it does unstick from itself and you can clean it off by brushing it. I cleaned the window thoroughly before application, and then sprayed windex on the glass, and it attached just fine. They are easy to remove by pulling, though.Edit: I decided it worked so well that I did another window with the same product. I used a trick on my windows, I got some black electrical tape to cover up the edges where I didn't cut 100% perfectly, plus the tape helps a little with adhesion, although I don't think the film really needs it.That was a few weeks ago now. This film is really great, I can open and close my window, and it isn't coming off or anything. I don't even need to think about it.

The best and fairly easiest blackout film. Unlike others, this one has perforated lines for cutting straight and it sticks to window easy with a little soap water, and lasts for years. Oh and it blacks out super good!

I purchased this window film to blacken out a small 44" x 8" window over our shower. The window is on the west side of our house and there is a large mirror opposite it in our bathroom. Early afternoon and evening sun reflects off the mirror making any use of the sinks or mirror impossible. Following the instructions of cutting the film to 1/2" larger per side of the window then trimming once the film is installed, is not possible. !st the film is a thick vinyl material with a paper backing. instructions say to clean window of grease and dirt then remove backing from film. using a spray bottle with a few drops of dish soap and 32 ounces of water, spray both the window and the back of the film. OK did that. placed film on window and squeegeed out the water in between Film and window. Here's where the problem begins. corners "do not" sit flat into corners of window. They will need to be notched. the razor blade knife required needs to be new. (sharp). trimming the extra material from the sided and top/bottom needs to be a full cut from end to end. the vinyl material being thicker than film will not allow you to do this without the material pulling off the window. I tried using a razor blade knife, a roller wheel knife, and finally a brand new scalpel. the edges are choppy and allow in light. The roller knife worked best but I was unable to get into the corners. and took a lot of pressure to cut through the vinyl, it made the straightest cut but because of the needed pressure, left areas uncut, hence the film is jagged all around. If you buy this material, I would suggest you measure your window with as much accuracy as possible and cut this vinyl with scissors as close to the measured dimensions as possible. at least it will fit without trimming. Also the material tends to stretch and move as you are squeegeeing out the water. GOOD LUCK

Having a bedroom that gets full eastern sunlight can be a bit of a nightmare, as many can attest. There came a need for my s/o to work nights when the world went sideways and dawn was no longer a friendly welcome - something had to be done. I'm not displeased with this solution.Pros:- Drastically darkens the room (not completely black out, direct sun can still shine in a tiny bit)- No glues or adhesives required- Straight forward to apply- Landlord friendlyCons:- Not 100% black out- Too much heat and it will slip - just had a corner do it, but after only 4 days in May.- Cutting it precisely for the surface is...a pain in the a** - recommend an art knife and a ruler- Rather easy to tear during placementUltimately my solution for the 2nd & 3rd con was not pretty, but is effective. I got a bunch of black electrical tape and I taped up all around the edges. No slip, no bits of light peeking through edges

I work 3rd shift, and need to have my bedroom to be as dark as possible for my sleep habits. I have tried other methods, and they just don't work as well. This product worked exactly as I had hoped. It is thick, and it blocks out almost all of the light from my windows. It is easy to apply, and I put it up solo even though it recommends having a helper. The reason I say "almost all" of the light, is because at the edges it is nearly impossible to cut the material so that it covers all of the window pane. There is a small amount of light that comes through on the edges. I also have room darkening shades that I keep pulled down, and those combined with the light blocking film help to eliminate virtually all light. All in all, this is exactly what I have been looking for, it is easy to use and apply, very reasonably priced, and IT WORKS! I would buy this again, and I would recommend this to anyone looking for an option as a light blocking window covering.

These sheets are very easy to cut up and install. The directions are written right on the back, along with 1-inch measurement squares. Sadly, after a few days of being up, they slowly one-by-one start to fall back down again.
