Key efficient, easy to implement and use with Orange, connecting by wireless or USB cable. It works even in case of very poor reception and has an SD memory card slot. It comes with a removable battery, a USB cable, a charger outlet to recharge the battery on the electric grid (you can also recharge by connecting the USB cable to the computer), two Orange installation guides clear and well illustrated, in French and English. I had three other key, different brands, working with another operator; they were less efficient and more complicated to use than this domino. Beautiful glossy white plastic case, easy to open. In conclusion, a very good buy.
