ZTION | UV Protection Heat Insulation Window Film

The sunshade glass film arrived with no smell, and the material and craftsmanship are pretty good. The size is standard, and it's reassuring to use.

This is super good! I bought one to block out the direct morning sun. I was worried others might be too thin, so I specifically got the 9mm one. Here's why it's great: Even though it's just a small piece, it won't drastically cool down the room, but without the direct sun, at least I won't wake up from the heat. Plus, I chose the suction cup style, so in winter or when I want some sun, I can just take it off. The customer service was also super thoughtful; they even reminded me when I accidentally ordered the wrong one. Product quality: high.
