The system with the clips allows for quick installation and removal.
During the initial installation, a little patience is needed.
They were installed in a Skoda Kodiaq. The only problem I encountered was that the part of the door that is closer to the fuel tank is slightly thicker than the one on the hinges, resulting in the clip that goes there not fitting 100%.
You may need to use pliers to "open" it a bit so that it fits properly.
The windows open normally. The shading is good. However, the price is too expensive.
They seem to be of good quality. Hopefully, they will withstand the conditions of the Greek summers and we will have them for many years.
In the photos, you will see the difference with and without the sunshades, inside and outside the car.
It comes in a special case/bag with instructions for use and a installation tool to prevent damage to the window rubber.

*** UPDATE ***

Minus 1 star because the clip of the rear right sunshade "flew off" and broke the plastic of the rear windshield. I had to go to the dealership to have it replaced. Most of the clips have completely wrong application. The rest of the initial evaluation still stands.

Quality product but expensive, gives a feeling of luxury, easy to install and disassemble, ideal for those who do not want to use membranes, either because they bother them or because they do not want to marry them.
