So what can I say I'm glad I found this cell phone holder! have previously always had the support one would always be attached to the wheel, but that have always solved by ne time and are always down slopes with my phone which I have always been annoyed animal! But since then I have this support for the vents I am overjoyed !!! If you have it once fastenings, then you really loose no longer! and the coolest is still you can use it for almost all mobile phone! simply top !!!
