This device is very compact and made very good photos. It is easy to carry in a briefcase or handbag. The battery has a limited but sufficient autonomy for a day of hiking. Still provide a second battery. By cons, WIFI function that interested me is unusable for several reasons: - The configuration is difficult or impossible on a corporate network - WIFI function consumes a lot of current, which is unacceptable for the battery capacity - WIFI flow when does work is weak, we can transfer some pictures in full resolution
