I have not had the opportunity to test it in a real situation for now (no good weather) but I can say that this is the original GoPro material with the quality that goes with it. I still mounted GoPro Roll Bar Mount Kit for assessing the quality of plastic and hardware as well as the engagement of the GoPro Hero 3 Black Edition with its waterproof housing.
The delivery was very fast: Control on Thursday evening after 22h and delivery on Monday morning with the standard delivery (fast) but not premium because my other article was not eligible.
It remains for me to test it on the bike and the bike! Roll on the good weather!
