This suction cup is easy to install on most dashboards, plastic suction cup lever is solid and does not seem to risk breaking (I bought it because the lever of his predecessor purchased elsewhere broke). It must be clean and degrease the windshield before turning on the vacuum and this takes a long time without coming off. This is better than sticking a support on a dashboard because the position is not always adaptable and suction cup moves easily on a bumper brise.ce model suitable for many phones because the jaws deviate enough. Personally, I preferred this simple model to a dedicated model (always more expensive) because it allows me to put a huge smartphone Samsung Galaxy Note with its packaging folded behind and is well maintained between the jaws, despite épaisseur.Certains the specific models require removing the phone holder to place it. The piece of Plexiglas on the bottom is used to put a picture or photo and I think it is useless because it is hidden by the phone, plus it provides an extra thickness. So I removed the background is black and no longer draws attention.C'est a good quality product for the price and in addition, simple and versatile as accept small or large phones like smartphones my galaxy note. He will not leave a trace on a chart bord.Il also accepts small GPS.Comme most simple devices, it seems to have been well thought to be versatile.
