Skeptical before buying and reading the various comments, I ended up taking given their very attractive price. No regrets: good quality mesh, for the life of suckers, I will not comment. The outline is deformable (much like the tents 2 seconds), it fits in my opinion to all forms of windows (personal Megane III 5-door) and the suction cups are in relief.
Compared to other products that are worth a fortune (up to 120 for the custom), test it.
