Niviy Excellent Quality 3D Static Cling Window Film Self Adhesive Window Covering Decorative Flower Privacy Film for Window 17.7" x 78.7" Black

This an awesome product & transforms the appearance of windows. Initially had wooden blinds at the front door sidelights that were sort of ugly. Removed those and installed Niviy decorative window film on those windows and look great -- allows light to come in and yet have the privacy. Very easy to apply and my wife trimmed one & installed in the bathroom window that looks into the dense woods behind the house. 3/4 of the window has the decorative film and the remainder is clear glass. Highly recommended.

My bedroom gets direct sun in the Georgia summer and the a/c can struggle. I applied this to our windows and now it is much better. The picture shows the top pane with the film and the bottom without. The amount of sun block is amazing!

Perfect for what I needed - offers the right amount of privacy while allowing sunlight to shine through the designs. Easy installation!

I wish that I could say that I had used the whole roll of film to cover a window or glass patio door.But, I only used a piece that was 12 inch x 12 inch diamond shaped on my front door to give me a one way mirror effect to enable me to look out to see who is at my door without being seen inside.And it works great in daylight or at night with my bright porch light on.I didn't purchase this product to block sunlight as it is advertised to be used for.

It works as described. It does a great job of decreasing the amount of light and heat that gets in through windows. It's almost a little too dark, but I can't fault them for that!The picture is a side by side of one garage door with and one without.
