VERY DISSATISFIED AND UNHAPPY. The watch does not turn on AT ALL. I follow all the instruction on the guide and DID the instruction provided by one of the customer service on the comment message on your facebook account. My profile name on facebook is Lhet Desputeaux. I am asking you Health watch to refund my payment or send me another item/replacement on this item. I am very UPSET and UNHAPPY on this experience.
