First good point: the camera comes "complete". Everything comes with SD card, various connectors, fasteners and fastening, waterproof housing ...
Anyway, once received, as usable and without spending one euro more.
Second good point: the ease of use. Once the language "French" selected, the installation is done alone. Certainly, it is regrettable that the manual is in German, but the camera is easy to use with a little patience and common sense.
Third good point: the result is pretty good. Set and tested on a bicycle handlebar, the rendering is relatively "immersive" and friendly. However, given the angle of view, the film made a distorting effect type "fish eye". This effect is characteristic of this kind of camera can be corrected with the right software.
It remains to verify its effectiveness under water, video-surveillance camera (trigger movement) ...
However, one thing is already certain: this Ultrasport camera certainly does not reach the quality of other brands such as Sonny, but is a true compromise for those who want to have fun without spending too much.
In summary: an effective board camera and accessories well served.
