Between each pay GoPro accessories 40/50 and pay a pack has 30 promo, what more, we make savings where we can! Everything seems correct and impeccable, the quality difference will surely over time but that price, one can not but be satisfied! The boom seems a bit steep and probably will eventually be seized. But for now, no worries. Recommended if you have fallen for a GoPro but that the finances of the GopPro accessories for you is too expensive.
