Review on 🌞 Coavas Sun Blocking Privacy Frosted Window Film - Non Adhesive, 100% Light Blocking Heat Control, Reflective Window Tint for Home Office - Blackout Window Covering 17.7" x 70.8" - Anti Glare/UV by Michelle Sanders

So far, so good! I wasn't precise with my measurements, so there's a bit of light leaking through them. I personally bought them to keep the sunlight out and hopefully keep some heat out of the apartment in the summer months. I didn't do all the windows, but I have noticed windows where I can feel a slight difference in temperature. If you're using these two tinted windows and sleeping, you should be able to take accurate measurements so the light doesn't shine through. They work as advertised. It's a little pricey, but for the functionality, the cost and usage is fair. They hold up perfectly, the more water the better the better I haven't used a bubble removal tool with just my hands, but it would probably be better if I had something to get rid of any bubbles that stay in place. Definitely worth trying and worth the money
