Pro:
1. Small lens unit.
2. Good movie quality (focus) on the day and night (natural color). Even against light sources (sun). Good compensation against bright windows.
Cons:
1. Unprotected lens (a rockfall or sand bath and ...)
2. Very low battery. Max 1h. Not interchangeable.
3. Battery only rechargeable in unit. Approximately 4.5 St. Toll, especially somewhere, out there.
4. Control unit quite large and heavy.
5. setting any parameters only smartphone available.
6. Only 1.5m waterproof.
7. camera can be worn only on the left side of the face by means of brackets. When driving a disadvantage.
8. cable between the lens and operating unit for short.
9 films are interrupted on the memory card after about 13min. (FullHD) and as a new piece of film again 13 min. automatically stored in a new folder. Say, a recording of about 60 minutes. is splintered into about 4 parts!
10. Bildstabilizator not working at the highest resolution just like the horizon compensation.
The camera is simply not thought through or ad painted with the red pencil absurdum together.
