The battery lasts for "normal" day trips without problems. Last week, + 15 ° outside temperature about 3:10 during continuous recording in Full HD !!! That's all I need. But for the "freaks" who sit on the bike 9h (Apparently there are), you can load the camera also on board network via MicroUSB and movies at the same time.
So here's my summary:
+ Rotating lens for Monday and really any surface
+ Compatible with the Drift remote control, so no annoying dismantling at mode change or recording
+ Display shows the color mode (Video = green = yellow photo, Burst = Pink, Fast Photos = blue)
Easy to change settings on the camera +, on-screen menu
+ WiFi connection (for iOS and Android, I think) to the Photos / Videos equate online / align the Live image
+ Battery life at full HD recording: 3: 10h (as I said, but I can go on and MicroUSB films simultaneously)
+ Built-in microphone (IMPORTANT: Motorcycling micro-sensitivity spin down completely, otherwise only wind noise; or external microphone use)
+ Incredibly small and incredibly light
As negative I would mention the maximum storage capacity of 32GB Micro SD, as other reviewers here compete with 64GB. At 32GB, although you get 8h video, only I'm just lazy in the switch.
If the camera can really highly recommend.
PS: Had before a Hero and this really can not keep up with the Stealth 2 (no WiFi, catastrophic battery life - especially when it's cold and no rotating lens).
