Incredibly nice action camera that produces really good results! Excellent user interface and battery life. Bought with a little gimbal as well and along with it the video becomes silky smooth. Top product!

Feels real stable, good video and sound recording. Bought me for 1580kr (£ 136.67 with express shipping) incl. Selfie Stick & Bluetooth Remote during amazon mid-month tour. More or less everything like a gopro :) + Real camera mount. + Large screen. + Single GUI and App for pairing with the mobile. Only 3 negative issues. - not waterproof without case. - Can not open the battery cover if using the bracket (would sit on the side instead) - no external mic jack There is a Yi 4K + that solves some of the negative things.
