The very strong point to the grip is very great and INTUITIVE SIMPLICITY of use, the menu is either on the back or the monochrome screen is well done. It is the same on the remote (I took optional).
The Fnac test reference on the matter, also confirmed my choice.
Because I wanted a good diver box (Gopro dropped his to -40m) NPC -100m so there was no picture!
Resolution 1080 / 50ims so beautiful. Forget the 4k 2.7k or Gopro unless you have a computer at 10000th! the processing of the video is huge for this resolution !!
Many supplied accessories screen (100th in gopro).
I have already tested the cam and it's great, especially under water and I confirm that for the moment no free with the screen and without anti-fog inside the box kit. (Cleaned inside the box before the first use, a film of fat is certainly present in the manufacturing)
Finally I would say a quality / price ratio top, go with GOPRO hesitation, you will truly not be disappointed!
