After experimenting with this type of device (a low-end Olympus) who ended up taking the water, which was taken as collateral, I offered this device there six months for rafting on the Verdon ! That happiness: great photos, HD videos of high quality, breathtaking views, amazingly simple, ... Whether on the water or under water: no complaints! And this winter I took him skiing above 4000 meters: no problem, photos and videos impeccable! Only complaint: the battery is empty pretty empty (especially video) and recharges slowly enough! Solution: buy one or more additional batteries (I have 4 in all) and also a charger (for the standard battery charges in the device, which prevents to use it).
