This support is very small, unpacking was afraid of having paid dearly, but the installation we see that is very well designed and very well made. Without quality manufacturing, such a product would quickly unusable because it would not last long attached to the air vent, or the phone would eventually win the support. Is a little expensive, but it should not be an item of great series :-) The packaging and the manual contrast with the anonymity of certain products manufactured off by who knows who.
