Xiaomi Yi 2 Review - watch this before you buy a gopro 4!!!

-> buy here: Cam info/shop

Really a decent cam! Sorry that I couldnt compare it directly to a gopro4 black. Maybe I can do this in a next video later. But it's better than every single actioncam I've tested so far.
I also will make a slowmo videoclip - since this is the first cam I have that can deliver 720p240 (8-10times slowdown).
I will probbably not fly the vortex with it a lot since low and fast in 4k is too much for youtube's codec... (it looks perfect on the raw footage though!).
Sample clips: 
RAW high flying 
RAW Low and Fast over field (hard for codec)

►Pro's and con's:
+ batterylife!
+ touchscreen: intuitive UI
+ image quality: stunning in 4k, timelapse mode works great, I guess 2hrs with full battery are in range
+ slow motion (1280x720@240fps) looks decent - quite sharp and gives really smooth motion
+ tripod mount integrated directly

+- pricetag (bad if you compare it to other chinese cams, not if you compare to gopro :)
+- gyro stabilizer: doesnt work nice in all conditions, reduces quality of course,...

- form factor: not gopro sized, own dimensions, only their waterproof housing will fit
- touchscreen: not easy to read in sunlight - and then setting the options is hard...


►Specs:
Ambarella A9SE75 DSP (this is more advanced than what Gopro4 black has, and it is way more efficient - the cam doesnt overheat, battery lasts longer...)
