The holder is very good! However, I have a small round adhesive pad with velvet surface glued to me so that the smartphone is in excellent hands and without chattering on the rear. When pushing the HTC One automatically switches to Auto mode and switches the homescreen. Simultaneously, the Bluetooth connection is automatically made to my car radio. The large suction cup firmly and securely hällt. Also, the insertion and removal of works flawlessly. I think the owner is the perfect complement for such a nice smartphone
