HTVRONT Blackout Window Film - Black Out Window Film 44.5 * 200 CM, Blind Reusable Static Cling Room Darkening Window Blackout Film, Light Blocking UV Protection Window Film Privacy(17.5 x 78 inches)

This window film went up really easily.Measure the window and cut the film to the required size. Then, after cleaning the window, spray it or wipe it with a wet, soapy cloth.The film comes away from the clear backing very easily, unlike some we've used in the past.There's a bit of leeway when you're putting the film onto the window because, with the soapy water on the glass, you can adjust the film slightly as you go to get the correct fit.There is a slight caveat with the black film, and it is mentioned in the seller's description above but worth repeating, when using the black film it does absorb the light and thus can become warm in the sunlight. This isn't necessarily a bad thing, but you should perhaps be aware of this if your windows are south facing, for instance, and the room gets a lot of sun. The window will get quite warm to the touch.So, easy to cut and easy to apply to the window. This seems like a good product.
