I wanted this phone holder so I could mount it on my desk or stand to record videos with my iPhone . What also attracted me is that it can be adjusted, bent and rotated 360 degrees, allowing me to shoot from different angles and different angles. This phone mount is constructed of heavy-duty aluminum alloy and consists of two (2) pieces: a three (3) adjustable mount and a phone/tablet mount. The first section is a tube with a base clip, the second is a tube that prevents the mount from falling, and the third is a gooseneck that can be bent and adjusted to any angle. The way this phone holder works is that you simply place the mount on the side of a desk, table or counter to a height of 3 inches and then tighten the spiral base clockwise to secure it. You must then loosen each knob to be able to move and adjust each section, which can rotate 360 degrees. The nice thing is that you can even remove a section entirely by deleting that part entirely if you don't want it to be too long or tall. It can be fully expanded up to 43 inches. Another cool feature is that it is compatible with smartphones of different sizes and can even accommodate and hold tablets with a maximum width of 9.5 inches, so it is very versatile and functional. It's the size of a tripod, so it's portable, but not as compact as I'd like. Also, it's a very useful device and now I can record videos on my smartphone hands-free!
