Good alternative to the expensive equipment

The corresponding brand devices were too expensive. I'm not the extreme athlete, but wanted to use them for bike rides and car trips in addition to the camera.
Fish in the pond I have already filmed.
Positive:
+ Film HD quality in order
+ Maintains water tightness
+ Battery I did not even get empty, but also invite after each use by, the longest mission was 90 minutes
+ Automatic charging in car mode
+ Car Mounts working class

Negatives
- LCD display so small that you need a magnifying glass
- Due to lack of display the alignment in your car or on your bike is always something like Lotto (too much dashboard)
- Bike and / or helmet mounts are not optimal thought in my opinion
- Operating too short and vague (eg I did not think you have to attach to the top edge of the disc on the head camera in Car mode, since the video is recorded upside down in this mode (PSE can indeed the entire film Ruck Zuck. turn, it would have been nice to know it in advance)
- Belonging to the camera software for connecting to an iPad works very slowly and only when the camera has 100% battery charge, otherwise the app depends on when downloading the movies, photos went; correspondingly slowly is also the live image display and timer function from iPad (speeds as at the beginning of digital photography ... who can remember)

Conclusion
Since the recording quality and battery performance meet my needs, I'll keep the part. The lack of quality micro bothers me less because I fulfill the movies anyway animals in section and / or Publish with music.
