The support I have attached to the windshield and they will not budge. Again, you have to have no fear that this could fall. There is also a small plate to stick on the dashboard, this, however, I do not use. In addition, even a sticker thereby to adhere only the removable mounting on dashboard (without squeegee). The holder can be with me solve a little hard from the suction cup, as this anyway should always remain plugged, which is not a problem for me.
The suction cup of the holder, although clunky, but it wobbles or vibrates anything while driving. Even at 200km / h on the highway has nothing vibrates. By two screws, the holder can be aligned accordingly. By the chunky squeegee can the holder is not quite as deep attachment to the windshield, especially if the bottom of the iPhone also the charging cable to be connected. You have to secure the cradle slightly higher, which could obstruct a little the view. Even with very sloping windscreens, the bracket must be mounted higher on the disc.
All connections are easily accessible with the iPhone 5, what was important for me because I want to the audio output (headphone jack) to connect my FM transmitter. I have the feet pushed slightly inward and can thus simultaneously connect an audio cable to the headphone jack and the Lightning charger cable to the Lightning connector.
Overall it's a great support. Strong buy recommendation!
