On par with go pro in terms of quality, the action footage (fast-changing outside scene) is fantastic, while inside and landscape shots are both subpar. The biggest drawback is a rudimentary Wi-Fi communication application that frequently fails, freezes phone images, and disrupts file transfers. Still, I'm content with the camera! Beware of fakes; the real Wi-Fi version is called sjcam (I paid six dollars for thousands of them on eBay). Video illustration
