Installation is very simple and for me as an engineer it was mounted on the handlebar in no time.
At the beginning I have always wound more rubbers from the budget to the device, because I really wanted to risk a worst case, such a broken display or complete defect in the iPhone. With Dr. time the gums have become less and now I trust the holder fully. I can test both on the bike and on the mountain (degrees jtzt in winter).
In most cases, the iPhone auto shutdown temperature and Displayablesefähigkeit itself stands to reason in the way. Therefore, the holder may not matter, because it keeps your device bombproof in the apparatus therefor and a stop while biking make no problems, because the device can be fixed by taking the bracket and then reattach it. Because someone has hard times and thought his brains. Top.
Both on the road as well as on cross-country tours did not disappoint the holder and am pleasantly surprised. The unit sits bombproof in the bracket and the bracket on the handlebar.
Only one minor complaint though it should be mentioned, namely those rubber bands supplied. They look very stable and witterunsgbeständig, but already I can see how one of the rubber has slight changes in the surface structure. Over time, the material is porous and therefore should be replaced for the safety of the appliance. These gums gets easily at the hardware store. I suppose most sealing O-rings in the appropriate size. While not black, but much more stable than the supplied one.
That bothers me but less, because it is a consumable item, which just is aging due to external influences. As just about anything.
Thus, a clear buy recommendation from my side.
