Loads of videos on YouTube about this vs the GoPro 5. The GoPro has the edge but no where near enough to justify the extra money. For the price the YI 4K can’t be beat. If the 4K plus comes up that is top notch
Buy the GoPro Hero 2018 and upgrade the software to the Hero 5. The hardware is identical. Makes the GoPro a bargain. That said, the Yi 4k is just as good a camera for less money. Just doesn't have the durability of the GoPro, so depends what you're using it for. Personally, I would go with the GoPro after owning both.
Main things spec wise are that the Hero 5 is waterproof and has GPS. Good review and comparison here: https://www.techradar.com/uk/reviews/yi-4k-action-camera
Can anyone comment on this against GoPro hero 5 or akaso V50 Pro?
