The first mobile arrived very quickly unfortunately it does not work at all it is true that the very brief packaging could be the cause. S The return is done without any problems with AMAZON and the second cell was delivered just as quickly as the first and functioned smoothly. The product is very neat and aesthetically very successful ,, quick screen and very clear graphics brilliant but unfortunately this is inconvenient for a machine that can operate outdoors (reflections) A matte screen would have here more reason to be. I take off a star (4 instead of 5) for its fragility transportation and brilliant screen. BUT thumbs up for its responsiveness AMAZON kindness its monitoring of mail and a full refund of the return costs including costs of return and insurance all in a matter of days The downside, however, for packaging (admittedly a small sturdy cardboard strolling in a large cardboard box with virtually no padding)
