Super sports camera and very close to the black gopro edition before 2014. Very good value for money. For me it is one that is the most interesting of all my research and testing that I could do since I possess. It is 2x cheaper than black edtition home gopro for virtually do the same things. among the less expensive it almost unique in offering the 1080p 60i / s the others are 30. However, the GoPro accessories are compatible not put the original clips on a supoort gopro gopro or branded as this can get stuck but hey you can just mix and without departing 3x times cheaper. The quality is there you have tested on karting. I would test this winter skiing. The sound however is much attenuated when the camera is in the waterproof case so the sound from your speakers are clear lol.Les menus, buttons work well, the iPhone app is great, and the remote but it's bonus quickly discharged. The camera discharges slightly even when not turned on. But a correction probably arrive with a new firmware.
