Hello, the Herbert Richter Car Holder for Samsung Galaxy S2 i9100 for attachment to the ventilation grill with a 4 ball joint, is a good and especially cheap way to place his smartphone in the vehicle in optimum visibility, without the need to lock out the windshield with a holder. The installation of the bracket is simple and can be quickly removed, eg for Fahrzeugwechsel.Das 4 ball joint is convenient when using your smartphone as a navigation system, because you can adjust the holder any again. As mentioned, it is a cheap option, but visually rather inconspicuous ist.Wenn it bothers still you can not use in the bracket with a small handle in the glove compartment verstauen.Bei one may this low price, of course, do not set expectations zuhohen how they zBbei fixed built-holders has. On the whole I can well recommend the bracket.
