delivered quickly, but can vary depending on vehicle type destroy the lamellae

The mount was delivered quickly within a day via Amazon Prime. The holder itself makes a very strong impression, the spring clamp for hooking into the ventilation slats is very tight.
The problem lies in the idea of ​​wanting to fix a smartphone with a certain weight of a holder with certain leverages to a single fan blade whose actual task is the redirection of air. You would of course have to come out of himself.

Long story short, in my Tiguan was at this air duct after one day use completely broke the slat adjustment and can no longer be adjusted now. This was certainly reinforced by the fact that it has exercised when inserting or removing the phone against the spring forces the holder additional burdens on the "low fin". Maybe this product works at another fixing point, by using the ventilation grille I would now strongly advise against.
