Update 15/08/2013
Unfortunately for now 2 months the upper lug of the holder is broken. This happened during a car ride without was applied to the holders Hand. I can only speak of good fortune that the Navi (Garmin 3597) is not pleased with the glass plate on the gear lever.
I would like to mention that was the holder of me after purchase 3 times on and degraded. This should not lead to material fatigue in my opinion. Whether this is a design flaw or something similar I can not judge.
