In the same case as Thierry, very disappointed with this kit. The instructions in multiple languages is more summary, the proposed photos are very small cropped. We have to try hard to ride but upstream understand the meaning of assembly. This kit is not intended for double doors wooden windows, which I also for the window used for extraction. So, I have not mounted, not unmotivated by the seriousness of this product, definitely too expensive. I have not returned, at the cost of return shipping, it is not worth the trouble. Be careful, make sure you have PVC windows of normal size, otherwise it is not possible to go all round.
