Heat Blocking Window Film, One Way Mirror Reflective Glass Window Tint Non-Adhesive Cling for Home & Office Daytime Privacy, Heat Control, UV Rejection, Glare Reduction(Black-Silver, 17.7x78.7 Inches)

It was a little small, but I should have ordered the bigger size, my mistake on that part. It is easy to install and it works very well. I can see the pond and the wildlife that is there is no longer afraid of me when I am at the window enjoying nature. The bright sun doesn't get through and that keeps the room at a nicer temperature.

I would not believe how easy it was to install this product. I simply sized the product with the window, clean and dried the area, removed the film, cut to size then I was done. Other than my cuts where the straightest it was unnoticeable. The install took about an hour start to finished. The next day it looked as if I had tinted glass installed. It is a bit darker then what thought it would be at night but I would buy the product again.

I bought this for a tall, narrow office window. I was worried that the vinyl would be too thin and prone to stretching. It is not. Any vinyl sheet will be prone to stretching, somewhat, but this material is sufficiently thick. The size was just as advertized.It is easy to apply, but requires some patience and preparation to apply it perfectly. I rushed and ended up with tiny air bubbles. The nice thing about this material, though, is that the lack of adhesive makes it quite forgiving. I was able to pull it up on the edges to let out air bubbles.As for the film's sunlight blocking ability, this material did reduce the light in my office somewhat, but not too much. It is very similar to wearing sunglasses - I can see the sun without it hurting my eyes, but not look directly at it.Here are some tips to keep in mind about this type of vinyl film, regardless of product or manufacturer:1) Follow the directions exactly. Watch some tutorial videos online. Get a rubber squeegee (dollar store). It is very tricky to put this stuff up without air bubbles, stretching the vinyl, and creating ridges, but it CAN be done.2) This roll is very long and narrow. Measure your window or glass pane before you purchase it. You want to avoid seams if possible. Try to purchase more than you need; then trim the vinyl after you apply it.3) When you lay down the film, it is nearly impossible to get it perfectly plumb/square/level. Thus, I recommend that you align the vinyl, tape the top, remove the lower half of the backing, and work your way from the middle of the pane downward. Then remove the rest of the backing and work your way up. In other words, work from the middle outward, as much as possible.Overall, I am very pleased with this product.

I suppose for clarity I should start by letting you know I'm American, not British. Thus, when I say I was trying to spy on a bird, I'm referring to a robin rather than a lady.With that part out of the way, I'll note that this was easy to apply, stayed up quite well, and seemed to work fairly effectively. It was a bit confusing trying to figure out which side to point out, but other than that it was a really simple application.The problem is I bought this hoping it would allow my kids and me to watch the robin that was nesting outside our kitchen window without her flying away any time we got too close to the window. Unfortunately, she never came back after we put it up. I'm not sure if she saw her own reflection or just a shiny new wall behind the next, or maybe the reflection heated things up too much. Whatever it was, this chased her away.I'm giving it 3 stars because it seems like a pretty good product, but for this specific use it was completely counterproductive. I suppose, however, this product could be quite useful in dealing with a robin infestation.

Bought this due to my window facing west and my room getting hot. Well not anymore. This blocks the sun a good bit and has kept my room cooler since install.

We got this for our RV and it really helped to block the heat but took some time getting it on the windows but was so worth it.

The roll had an air bubble crinkle about 5 inches long in between the adhesive paper and the film itself that I hoped would come out if I installed it and tried to push it out. Nope. It was manufactured with the air bubble in it so it was set in its ways. Straight to the trash.

Without a doubt, FOLLOW DIRECTIONS. This stuff is easy to apply but patience is required. A room in my house used to heat up with the morning sun by 9am regardless of outside temp. The window film now keeps most of the heat from the sun but allows light, and all the air can be pushed out during application with patience. Be careful not to stretch the material.

Did it like it told u in the instructions...which is simple, done it before with other stuff, goes on easy and quick...2 months of super hot summer and it's still on like day 1...makes a huge difference in heat reduction. Will buy again!

I live in an apartment and these changed my life. Summer is unbearable with my AC units barely keeping up on 30 degree (C) days. My apartment has one wall that is all windows and these helped keep the heat out so much! Very easy to install if you follow the directions. Worth every penny.

..which is usually a good thing, but I'm missing my bright, sunny kitchen! Not totally sure if I'll keep them up, but they really do a good job in keeping the sunshine (and heat) out. Would advise that, in prepping for application, you use plenty of liquid to make the installation easier.

Worst window film I have ever bought. This product is see through. It is not a blackout film. Tried installing it multiple times and failed. Bought 2 other similar products from other brands and they worked perfectly.Super hard to instal, dies not stay in place, is somewhat too rigid. I did follow all the steps, OCD cleaned the windows then make sure absolutely no residues if any product was left.I definitely do not recommend this product at all.WIsh I could get my money back as it was more expensive then the other ones I bought without even working properly. Major fail.

Too small, but the largest I could find.
