This mount is advertised as a tablet mount. But you can also use phones with it. You just have to position the clamps on the phones long way instead of the short way. This makes it a one size does all for you. The mount is mounted via screw hardware and is included. Each of the joints can move in any direction within its plane. You can mount this to go sideways or up and down motion. Depends on what you want it to do. The mount that holds the phone or tablet can adjust to any angle. The device mount is very easy to use. You can set the range you want the one clamp to be and the other clamp is spring loaded. The clamps feature soft material that will grip your device without causing scratches. The clamps are wide enough to hold a variety or tablet brands with or without cases.
Each of the joints can be tightened to a degree of resistance you want, by using the included allen wrench. The mount arms and base are made out of machined aluminum and with a painted finish.
Finally, the you can fold the entire mount system in when it��s no longer in use. Making it unintrusive and it gives of the minimalist organized look.
