Certainly it fulfilled its functions. BUT !! Prime very negative, something vibrates inside! And when I drive, something that almost vibrates constantly, I have LOTS of bad ... Then he is not moving! Frankly ... An air vent phone holder that is not moving ... What to say. The worst thing is that I bought this for my wife, just because I had a prior model (same brand and everything !!) in my vehicle and he was awesome. So, I'd like choices: Make a "trick" that vibrates and does not look or you want to my wife, or give him mine and recover it ... "Truc", which I already feel will not stay long hooked to my air vent by constantly GrRrrRzzZZzzzzz ... I am very disappointed.
