After gopro comparative and other value for money is to go! even my friends envy me! I just tell them my "GoPro Chinoise" is waterproof and searching on the internet a product overview can be trusted. "Jtgeek" (jtgeek.com) adjustments are made only through the smartphone wifi. the video files are the .MOV to know. both batteries are there. and for a small user to diversify the camera views at 100 is perfect. I do not do that base jumping weekend or speed riding all winter. For most people this camera is powerful enough to meet your needs. Shots of tricks is also a key to have cool videos !!!!
