The shipment from China has initially chopped something, but because of the extremely exemplary customer service to the theme was positively accepted and the camera came after very quickly. In the version with 2 batteries Everything is ready here. Have the camera already able to test quite extensively, whether mountain biking, playing basketball or underwater. All the best. Also with me the image is compared with the GoPro slightly bluish, but still very good. Sound is impeccable, even hidden in the underwater housing, the sound comes easily. The camera will do exactly what they want and extremely fun. Just the app makes funny business. When Note 3 and Galaxy S4 my connection fails for device. On another S4 and an iPad, it works. Price / performance level. Recommended as senders Boom Yours.
