In very difficult lighting conditions (eg in the forest), as well as stronger vibrations (eg in a fast downhill) but you have to live with restrictions. The video clearly lose sharpness and the vibrations cause waves in the image (according to rapid and competent information of an employee of Actionpro should it involve to the Rolling Shutter Effect). When mountain biking I have tried and found that the images at the assembly in the fork or handlebars (straight through the vibrations) act indeed spectacular wheel mounting, mounting in the area of suspension fork and a helmet mount, the quality of videos helmet mounting (by much better to evaluate lower vibrations) but is (corresponding brackets Vented Helmet or for steering wheel assembly can be purchased separately as an accessory).
I suspect skydivers, paragliders or diving, etc. the greatest joy will have with the device because less vibration safely allow a sensational picture quality.
I have long wondered whether I should forgive 4 or 5 star and I do not have -. EV also reworked videos apart on the Internet - the compared to similar products (eg Gopro, etc.). Basically, however, I have convinced the videos and I guess similar products are similar to have problems with very low light or with vibrations.
I therefore forgive the full five points and speak from a buy rating.
