The order received almost a month after payment (delivery to new mail). Corresponds to the photo and description. Instruction in English and Chinese. In the instruction (on the Angl. Language) we scan the phone QR-the application code dayband, install it. Turn on Bluetooth on the phone, make pairing with the watch, enter your data. I studied everything with the "Tyka method". The strap was difficult to remove, I had to apply force-it is necessary to pull and it is removed. On the one hand, when you remove the strap-charging the watch, inserted into the charger from the phone. Charges quickly, the first charge lasted 5 days. The clock is controlled by one button: one press-overflow, pressing with hold is the choice of the main saver in three designs. Clasp is strong, the strap is soft, comfortable. I'm happy for hours. For this money is quite normal hours. Let's see how they will work in the future. Seller recommend. Thank you very much!
