Better than expected, but one should keep in mind:

I wanted a Cam for model aircraft and by TBS (Gemini), I came across the Mobius. On youtube short nor the lenses compared and it has become normal.
Next you should remember:
The case of the really small and lightweight (39g) Cam is rubberized (feels like). That's good, because it slips a not so easily from your fingers. Exactly this rubber is the holder but a problem because there keeps the glue the Velcro hardly. There is also a video of "Flite Test" where this is clearly because they have lost a Mobius exactly why.
Solution for me: Attach the holder Velcro (cuddly side), cut from below using the craft small slits through the Velcro (at the points where the holder has the 4 slots) and both stick together with superglue and activator. Keeps now for some really wild flights and hard landings.

By the way: The Velcro decoupled apparently so good that on my EasyStar2 despite Klappluftschrauben no Jello effect occurs. When a copter but you should then probably decide on a reasonable Enkopplung. Besides, since there's a cheap way of 2 credit (or similar,) and ear plugs. In "Kopterforum" is also a great Mobius thread with many tips and tricks to gimbal, decoupling, underwater housing and image settings.
After downloading the latest software and install the latest firmware everything is super.
Unfortunately, the advertised in the German instructions being sent with German Support Site is currently (7:09:14) not ready yet, so you get the English software from the .com version.
The image quality and settings on the software are absolutely above the price of Nivea under 100th
About the aspect ratio of GoPro (or similar) and that of the Mobius one need not discuss. Many in need of the GoPro, some people of the Mobius.
And now I'm curious if there are also of German mail COOLSTF eK the little goodie, because this was so far without complaint, but is sold degrees again.
