Very good product, I have a sports car with a hard suspension, with which we feel good every bump or stones, I had a support that pinched my smartphone and I had more than once to catch flight !! But with this support, my smartphone yours very well, and no longer falls despite shaking. The only problem I had is to successfully attach it correctly on the ventilation grille, but once in place no problem.
I think it's the perfect universal media, there has made a choice to make: fixing ventilation grille or suction cup.
