KESPEN WINDOW FILMS One Way Daytime Privacy Heat Control Anti UV Non-Adhesive Reflective House Tint for Home and Office, Black-Silver, 35.4 Inch X 8.2 Feet

if you take your time to really clean your windows, measure them properly, and use LOTS of soapy water you should have a really good result. The soapy water helps the film slide into position without sticking until you use the squeegee to get it all out. I purchased a film installation kit too so everything was ready right next to me. The challenging part was keeping the film flat enough to peel off the protective layer. I need my boys to help with that part. My tip would be to peel little by little and spray as you go so that the film doesn't fold into itself and stick. Once the soapy water is on the film and on the window and its pretty easy from there. Im happy with the result.Update: I moved out 2 years after this post and peeling it off was very easy. No residue on the window at all. It peeled right off like a screen protector off of a phone. I will re purchase for my new windows.

We have a large home with older single pane windows. Even with a brand new AC system, the house gets warm. We have double sliders in our family room and it gets pretty hot during the day. We tried this on the sliders first. Because they were a large surface, it took my husband and I both to apply it. It took approximately one hour to do all 4 sliding doors. It has a nice mirror finish during the day and the room was noticeably cooler. It also removed the glare on the TV. In my picture, you can see one side of the door with the tint and the other with nothing. Big difference! It darkens the room similar to putting on a pair of sunglasses. We just ordered several more rolls to add now that we are confident that it will make a difference.

The item is easy to use on glass. I have used all of my window and it looks it block the sun. But when I stand near the window I can still feel the heat is coming through the glass which makes the room hot. So may be it works 10 to 20% and that it.

The first picture has one window done. The second has the top three but not the bottom three so you can see the diffrence. About 10 min start to finish per window for installation. I suggest lightly spraying (misting) the window before applying, buying a rubber edged smoothing tool to smoothe out any bubbles/excess water and using a metal rugar and box knife to cut away the edges. VERY happy with this product and it only has a very light mirrored finish on the outside so it looks very nice as well. Great transparency, can still see very well outside.

Es una película bastante gruesa, hace ver la ventana fea y la visibilidad es opaca. El efecto espejo no brinda privacidad en distancias menores a un Metro. Es un buen producto si quieres ponerlo en un lugar poco visible y transitado, de lo contrario busca una opción distinta.
