Simple but effective! This product adapts perfectly to the air vent of my vehicle (Mazda 2). These two different notches allow it to adapt to thick louvers or purposes. My iPhone is held perfectly even on roads in very bad qualities! And no need to remove his protective shell! Last thing: contrary to what I read in other reviews, you can perfectly orient as you want (portrait or landscape) without having to remove it from the grid! In short, I highly recommend this product !!
