This GPS support (used with a samsung galaxy ace) made me service during eighteen months, with use of only about twice a month ... until that lost right in Bordeaux, I wanted the use ... well? I could not, I found myself with a lot of various and varied small parts (spring, screws ...) in hand. Well, it's cheap but it is better not to use it daily. But I still accurate than when I used it held its role perfectly (held in place on the windscreen, is based on demand to fit my vision ...).
