Sound Quality:
Totally unacceptable - and rattles mumpft as 8bit with 4 kHz sampling rate, even without the housing sounds even worse than any central language phone.
Image Quality:
Most overexposed, terrible dynamic range - with uneven illumination eat whole image regions cruelly from.
Contrast too high for too colorful.
The CMOS image chip with 11 MP is reduced with an inferior strategy on video resolution - not quite as bad as "nearest neighbor", but it crumbles but tidy.
Wide shots contain happens to a lot of details, and there is a reasonable image processor would be asked.
Only the low tendency to jello effect ("Jello") sets the camera positively from mediocre cell phone cameras.
Features:
In this price range, there are tons of "normal" digital cameras with LCD screen, a "real" zoom lens, charger and operating elements.
For the high price you get here 2 buttons, and a few neat produced plastic parts.
Processing:
My copy was (unopened) in their original packaging. Nevertheless, I have a fat fluff in optics, which presents itself in all resolutions.
First wanted to clean the front lens, the cabinet, until I noticed that it is an inclusion.
The back wall was filthy factory, the frame around the lens up also.
Operation:
If the two-key operation would not even anprechen delayed, you could get used to it.
The nuts for the screws just fall out when you loose screwed latter.
Conclusion:
Would be an established camera manufacturers (Canon, Nikon, Panasonic, Samsung ...) to make this profession, and obstruct rational components (image sensor, image engine, LCD ...) on a Action Cam, GoPro would look quite old.
Recognize the positive side, the mounting accessories and the style of packaging.
Bottom Stricht it works for me but as if here a company developed a camera that simply does not have enough know-how for it.
Excellent is at GoPro alone marketing.
