This support is very correct: the cup is equipped with a spring "sucker" effective. The clip is very solid on the windshield (a friend had a TomTom Go with a suction cup "to hit" ridiculous. Here, it's tough). A screw is used to tighten up the phone once suitably oriented. The phone him firmly, very firmly attached in its housing. That's why I take one star (it is too but you can not remove a half): I have the impression that the phone is very tight, it will eventually be marked by plastic. But hey, that's just me.
Access to dock port is easy. Last useful refinement of the phone is the attachment hole as it should, just the right size, ... at the camera and flash. In case you want to film the road, you never know ...
