I already bought this type of article but with another provider I hope he will be stronger because in principle the plastic tabs that hold the springs break over time especially when maximum distance with smartphones 5 , 5 inches. However it is flexible, it does not force, that holds up well to the gates (tested recently polo, Modus and Ds3) and at that price it's still a bargain. Also ideal if you rent a car abroad to secure your smartphone, it takes up little space in the suitcase.
