Used the bracket with us with an iPhone 4S. The device can be quickly and safely lock it in the holder and remove just as easily again. The clamp is equipped with such a kind of foam rubber and holding the phone even with potholes safe. The holder itself can be easily attached to the windscreen and has securely held despite low temperatures. The only complaint and reason for the "star deduction" is that the mobile phone bracket but significantly vibrates. This is probably due to the ball holder. The mobile phone can be read but still good and also does not change the set position.
