I was excited when I unwrapped but use it sucks. Battery has no autonomy, accessories are more or less good qualities, such as with the waterproof case, push super hard on the button to make a movie or take a photo. The smartphone app is poor bug to death. My friend who was with me has a Go Pro Heroe 3 and it is far better, he has recharged his camera only 2 times in 10 days while I did it more than 5 times. At that price I thought getting a good deal but the result is not at the Go Pro. Disappointed!
