The complete package.

I first hesitated on the full package or just the chest harness pack + fixing bandage on head for about 5 euros less. Indeed, it was not the telescopic stick, which critics on the full package suggested he was not up to par. When I saw that same stick (same brand and same design) was sold to 15 euros alone among different merchants Amazon or my area, I told myself that I did not risk anything.
The chest harness + fixing bandage on head is a very good price / quality ratio (for use as I do, ski, bike, etc ...) versus the GoPro brand. When batting, I do not regret the extra 5 euros, because I never would have bought at 15 euros elsewhere. For now, he does what is asked of him, I did not have enough back in time.
