Like all Anker products, the mount arrived in friendly easy-to-open packaging. Included within were the expandable phone holder, sturdy adjustable arm with suction cup base, brief welcome guide, and Anker product feedback card.
Assembling the mount is a breeze. The two pieces are attached by a ball-and-socket joint, so simply unscrew the large plastic nut from the socket on the back of the phone holder, slide it over the protruding ball on the end of the adjustable arm, and screw the nut back down. The joint allows the phone holder to swivel in any direction to accommodate any phone orientation you desire, but the proximity to the squared-off end of the arm prevents the holder from tilting more than ~30° or so in any one direction. As a result, only about 60° of the arm’s impressive 260° rotation range is actually useful if you intend to have your phone’s display roughly perpendicular to the ground. I didn’t encounter any mounting problems due to this limitation, but you may run into trouble if you attempt a more extreme mounting angle.
