The answers came to investing then saying:
Question # 1: I do not really need, but has become one of my favorite toys and I drag with you everywhere, from motorcycling over rollerblading and even for walking and mountaineering. It is believed not how funny it is to take in situations where things everyone else his camera retains fearing for the device in your pocket.
Question No. 2: I originally had the Silver Edition in mind, but I was the Wi-Fi controller then but to BE can grab as they unit_cost the price jump from SE justifies in on BE. Otherwise would be even better recording to mention.
Question No. 3: After much research, I gave it to find an equally good but cheaper substitute. There are currently no.
The processing of the camera is as so often mentioned very high-quality and leaves nothing to be desired.
The software problems: I have all updates made which were recommended and may complain about anything except for a small pause in camera. The important thing is, as with all appliances: Piano Piano. If they are overwhelmed by too quickly pressing and adjust the settings they can sometimes come in late and expect a little bit longer. I personally find but not bad.
Mounting via adhesive pad: On my motorcycle helmet this pad keeps so well that I would have to destroy the helmet to remove it again. Elsewhere I have not yet installed, I prefer to use the extra purchased is head mount or the poles.
The recording quality: I have to say I was simply amazed. The sharpness, the sound quality, everything is just perfect. If a suitable setting (720p or WXVGA) is unmatched slow motion can be displayed. 4K or Cinemode the resolution is so high that at the moment no device is available (in my area) to take full advantage of this, in fact I can not comment further. The recording Full HD (1080p) are smooth and sharp. Only sometimes I would like to see a manual focus, but let's face it, there is an Action-Cam, whoever has to focus time already? The photo quality is only moderately useful. In bad light, the image is often blurred. Even in bright light, it takes from triggering the photo a little but too long now, but it's not a photo camera and therefore should not be gmessen it. Shots burst counter function properly (in daylight) and Timelaps also.
Accessories: Here I must briefly swallow, because up to a minimum is at the camera with nothing. No charger (only two charger for USB sockets, one for camera, one for remote control), no memory card, no additional mounting options, etc. you have to buy everything, but everything there what your heart desires, just in return for the wherewithal , It must be said that the components move but in a moderate price range and have a generally very good quality.
Transfer to your computer: goes smoothly and quickly with PC and Mac. Camera is detected without problems and data are displayed.
Conclusion: This camera is (partly sadly) to which I think is only really significant out-door action cam on the market and fulfills its mission with flying colors in all areas of the extreme as well as the mainstream sports. I just love them and drag them everywhere thus. To record Just thinking everything led me to many more sporting activities than ever before!
