    Abbastanza soddisfatto
    Purtroppo ho ordinato un prodotto VERDE ma purtroppo è arrivata ROSSA. Ma questo è un problema non così rilevante. Il prodotto è allineato con la spesa effettuata, comprata sopratutto per il costo abbinato al GPS integrato.
    Purtroppo ci sono alcuni limitazioni di comunicazione tra smartphone e dispositivo e chiamate ed sms non funzionano sempre, ma ci sono alcuni problemi, magari verranno risolti in futuro via FW su android 9.
    Buona costruzione ed affidabilità misurazioni.

    The F21 Smart Watch is easy to use and the functions are simple.

    Use it anywhere and it looks fashionable.

    Screen is large enough for quick glance.
