    Parcel arrived quickly. Without damage. Look good. Working hours, functional matches. All functions work. Blood Pressure is measured quite accurate, we must adapt. Charge, active use, 2,5-3 days. Charging is very convenient, bracelet should be removed with force, can be broken. Directly to your laptop connect failed, need a USB extension cable, or connect directly to charge. Not always comfortable. IN general, a good band, functions, you can take. Advise and bracelet and store

    Great store. Send it right: fast and correct way. Accordingly came too quickly. The bracelet is made with high quality. Of Course after Honor 4 screen seems примитивным, but all you need to show. The Most interesting is certainly pressure measurement and ЭКГ. Readings with the usual tonometer-variation within the error in 3-5 units. The ЭКГ can not say anything. The biggest disadvantage is soft. To huaveya far, hope will it grow. IN general, and goods and especially seller of.
