This small camera brings an incredible quality of picture and sound. I see no need for the big brothers with a higher resolution, because the files are too big (15 min film are higher resolution then quickly even 2 GB in size). Even my concerns regarding photos in rooms and not enough light were quickly dispelled: significantly better than phones definitely. Operation front of the camera is something gewöhnungsbedurftig: before use once try. The small price enticed until you realize that no memory card comes along and maybe you still need a bike mount and one for the bike, a Brustburt, a holder for the skateboard, or a head strap. It's that fast again away some money. Original accessories are more expensive than no name, from my experience, the original accessories, however, is qualitatively better. The sound was surprisingly poor first, until I realized that the camera is in a waterproof housing - and the microphone also. The housing can be removed (fixed on the black lever pull) and - buy a small frame - as other accessories. Then the sound is also very good. Conclusion: cool thing makes great fun.
