THE watch is excellent. THE main point is the battery. Am using five days since the first charging full, and yet there are 60% charge. In relation to functions, also am satisfied. Maybe the heartbeat meter not be accurate, but other functions are efficient. With the watch, for example, is possible forward and rewind songs, something important for who like running or walking listening to something. Finally, the device has cost-effective. Recommend to everyone.

Good clock, but inside the square display, which can be seen through a round window. And so by the clock there are no complaints.

I took as an alternative a simple electronic clock. Already 3 weeks without recharging. Regarding the measurement of pressure readings, pulse, etc.-the device pressure measures and shows 110/70 even lying on the table. In principle, as for hours, I'm happy.
