The extendable tube is the same as for other distributors but 3 times cheaper seen other accessories. - The strap is too short, it is a little elastic but not suitable for the hand of a big burly, this is not really capital. The tube is hard enough to unfold, but it is not running and it is rigid. - The small wheel clamping the support (top), is a bit small and you have to have a lot of strength to well tighten, forcing the GoPro turns a little, but it is not loose, the whole can also save the camera in case of impact, as there are chances that it bends or turns it. - The diameters of the holes of the GoPro mounting system worth slightly enlarged - The frame is easier to planes if a little cutter 2 slides on the sides, front, over half of the top, like this, there is less need to twist the plastic that eventually break. I do not know if the original GoPro has this defect, but considering the price of the truth, a few tweaks do not mind. We do not see much in the picture, but it has a screw adapter for 1/4 "and another with standard GoPro click.
