With the Joby GripTight GorillaPod Video, you have complete control when you record or photograph with your smartphone. In the included holder, you can clamp a smartphone of 2.1" to 2.8" or 2.7" to 3.9". This tripod has flexible legs with which you attach a smartphone to a pole, branch, or tube. The leg stands on the bottom are magnetic. This way, you can easily place the tripod on a sloping car hood, or attach it vertically to a street lamp. There's an operating arm attached to the ball head. This lets you rotate the camera 360 degrees to take a stable panoramic picture, or tilt your phone 135 degrees up or down.
Note: the maximum load capacity is 325 grams.
