This mount I use now for several weeks for smartphones Archos 53 Platinum, the Archos 50b Oxygen and the Prestigio DUO 8500. All Phones have a secure grip, even if the holder on uneven roads fibriert something. The installation was very simple. The adhesive pad on the dashboard placed, and secured the support by means of the suction cup Smartphone clamped (without problems, but at some firming) and you're done !!! I am very satisfied and would recommend this holder for a purchase!
