Very good build quality. Comes with a wrist strap and a carabiner. Length with GoPro 40cm to 110cm. Important benefit is set as you want; Adjusting the length, 1/4 of a turn and it is locked !!! 2nd advantage: being able to deport the camera relative to the axis of the pole; We see less or not at all perch in the video. In short, THE ideal perch for Gopro !!
