No buttons to push, or metal plates stuck to the back of your phone. Simply slide your phone into the gripping arms of the holder and let the weight of your phone pull it down and lock it into place. Thanks to the gravity design, the CMH20 car phone holder makes it easy for you to place and remove your phone in just a few seconds whenever you need it, using only one hand. But that doesn't mean that a little bump on the road can represent a threat to your phone. On the contrary, the CMH20 has a firm grip that will securely hold your phone in place even on bumpy roads. It is compatible with all 4.7 - 6.7 inches smartphones and can be easily mounted in most car air vents. Moreover, you can use the included 3M adhesive to fix it on the dashboard. Need to recharge your phone while driving? No worries! The CMH20 is specially designed to offer easy access to the charging port of your smartphone for any cable. The holder is adjustable, offering the option to rotate it 360° in order to get the best viewing angle.
