Satisfied
Satisfied.
Positive points: it has several modes during the day.
Quite practical to hold.
I like the fact that you can use the front or rear camera.
Underwater is fine.
I didn't set it to 5K because all the materials and storage have to follow afterwards.
Negative points: It tends to heat up quickly, filming at night isn't necessarily great and you need several batteries.
It's a pity that the battery charger alone isn't provided, because leaving it in the case heats things up a bit.
The power button to turn it off is a bit hard I find.
On the whole, I'm happy with my purchase, for travelling, for going underwater and for sports videos.
