The windows are clean so I can see outside. I like that it sticks well to the window and doesn't fall off and it's thin.

As soon as I received it, I tested it on the living room window, and it stuck well. It was thinner than I expected, but it was thicker than the railings in my house, so I failed. It comes with a Korean manual, and the noise level is better than I expected. I wish I could see the clear outside quickly. Other than the customs clearance process being a bit long, it's good.

If you read the user manual carefully and use it, you can clean it without stains.
