    Well, here I am with smart watches. Came already charged. The application could not be installed from the instructions. I had to install through the App Store. But everything connected without problems. I will say so after the day of use. Steps measure do not understand how, there is no trust. I drive, and the clock counts the steps. Strange. Pulse measures less like. Pressure as said useless measurement. Lies without God. Notifications come, but not from all social networks. Well, so just a fashion accessory. Yes, and themes change. The choice is huge. In the water did not check and I will not

    The clock is good, everything works, but the herobandiii app does not connect, in the instructions of another application and it frankly speaking shit, but alerts work, SMS, calls, wats, I took it for that. Maybe someone had such a problem with the connection. The clock because of this in English, but Russian notifications.

    The watch came 25 days after the order. The parcel was tracked normally, even the seller helped to update the status, thanks to the seller for communication. The watch came in a box, the box is whole and well packed. The second watch was ordered without a box, but it didn’t stop. All watches are whole and please us. I definitely recommend the seller, I will order something else in the seller’s store. Thank you very much.
