It doesn't fit perfectly (which is normal since it's not made for a specific car) but it gets the job done. It was tested on a Golf mk7 on both the front and rear windows.

They do their job and provide satisfactory shading. They allow you to open and close the windows. The only negative is that they make noise when waving in the air.

I bought it from two different stores and there was a difference in dimensions. From one, it was big and even had extra, and in the other, it barely covered the window. On the positive side, you can have the window open. The quality will show over time, but for the money, it's fine.

Very bad application. In two cars that I tried, a 2003 Yaris and a 2009 Yaris, it was difficult to fit in the rear window. Also, the material smells like plastic. A similar purchase I made about 2 years ago, for the same price, the other product is much better in terms of fit and material quality

I used them a little since it started raining, they look good, I never used the stickers it contains... but I believe it protects well from the sun. However, I will come back since their use was not for a long time

I bought it to protect babies in the back seat from the sun. It works very well for this purpose, with the advantage that you can open the window without any fear. Also, when it is parked in the sun, you can have the rear windows slightly open to ventilate the car without worrying about anything getting inside.
The only downside is that they are a bit big, resulting in them wrinkling. I have a Ford Focus 2008 model. I read in the comments that for some people they were small, so I was afraid, but in the end they are big.

Do not expect perfect fit within the door frame, (the window fully covers it), but it fits in any window the car has. Very good protection, opens and closes the window without any problems. If you don't have tinted windows, it is a must-buy for the summer, especially if you have a small child

Amazing sun protection, it has saved us!! No suction cups coming off, no insects entering through the window!!! Very good shading and it doesn't hinder the airflow at all, also it doesn't interfere with the window's operation!!!
