    US03 Smart Watch.
    Article de bonne qualité et conforme à la description.
    Avec l'activation du bluetooth, la batterie se vide trop vite.
    Le Logiciel de gestion à installer sur le smartphone et aussi trop gourmand en batterie, sur mon zenfone 2, où la batterie me tiens a peu près 2 jours en utilisation standard, si j'active le logiciel de synchro et de gestion de la smartwatch, la batterie du portable ne tient même pas une journée avec toujours une utilisation standard du tel.
