Device very pleasant to use, with dual sim card, which is welcomed. The reception is excellent, the quality of impeccable sound, correct pictures. Usage is fairly intuitive. In short, many good qualities for a very reasonable price priori compared to what exists elsewhere. Only drawback, very limited battery life: it does not take the load on a day when I only use very few applications ... and big and only defect: the battery is integrated and not removable. After a washing machine by passing the first purchase of a new appliance 1 month later: still the same qualities, and always this limited autonomy ...
