We have now bought the 2nd belt, to have one in each car and not having to always umstöpseln (fits definitely in Citroen and Peugeot). I stöpsele the belt but only in the middle belt holder and a draw in then the Split rear seats in the trunk. There, the dog is strapped (with utensils). The strap is long enough that our dog lie comfortably in the trunk or sit (and can look out of the window) and also not in danger to plop from the back seat. Furthermore, it can not operate so inadvertently the Gurtöffner and he can not jump when you open the trunk hastily out of the car (to my mind all benefits). The belt is very stable and chafed so far (3 months) in any way. I am very happy with the product.
