solardiamond Privacy Window Film One Way Tint for Glass | Blocks UV Rays & Harmful Sun Light | Easy to Install Self Adhesive to Reduce Heat in Your Home, Car & Office (40 in x 15 ft) 20% Medium Black

Although it was easy to put up I was very disappointed that it had marks on the beginning of the roll that would have been noticeable had I installed it. Had to unroll it half way until I could find a nice clear area without any marks on it! Wasted half the roll!

This window film works, but it is VERY hard to work with. If you have the right cutting tools, if you have a VERY clean and VERY large work space, then you will STILL have issues trying to peel off the film. I would only recommend this product for professionals with the experience and tools to use it. I am a VERY experienced DIY'er and I would have to say that this project has been VERY annoying!

Takes awhile to get it on correctly. Once it was on it is perfect. My daughter burns just riding in the car. This has helped a lot and the car feels more comfortable because it blocks out the heat of the sun.

This film definitely helps with blocking the sun out. Made a huge difference for me once installed. A little tricky to install but once you get the hang of it, its not bad at all. Definitely a 2 person job if youve got larger sized windows. Trim the film a bit bigger than the window, wet the windows thoroughly, be patient and make sure the windows are extremely clean. If you do so, itll make the install much smoother.

You can see out and anyone looking in will only see a reflective surface, it may help a tiny bit with noise and energy savings as well. It is tricky to put on without making wrinkles but if that's not an issue, go for it.

Used this to cover store front windows. Completely black on the outside and can see out on the inside. Very easy to install and plenty of instructional videos online to help install. Simple set-up and installation. Had no issues installing.

This was a life-saver during the hot Texas summer for our second-level apartment. The effects were instaneous as soon as I put them on the windows.

Hard to install but has helped with sun shining through a front window.
