Very simplistic but works

The instructional videos are in Chinese but the user manual and all other aspects of the app are in perfect English. Its a good camera. No optical or digital zoom on it. Strong fish eye effect. Sony CMOS sensor. Comparable or better than GoPro Hero 3. For a fraction of the price. Except for the protective cases all other parts are interchangeable with go pro attachments. Check out Chinese websites to buy this camera and Go Comparable accessories.
