I found this as the cheaper alternative to GoPro with 4K recording and WiFi, ordered one last week, used it and looks more than decent for the price. Great reviews all around, for the price it is well worth if you're after an action/underwater/helmet cam. Specs below.
Get ready for your next adventure with the Kitvision 4KW action camera, with 4K Ultra HD video resolution, Wi-Fi and a built-in high resolution 2" display.
