We have been using it for 2 days, so far all the tests have gone well, the pulse is measured in the same way as a pressure measuring machine, the steps are measured with an error of about 5 steps per 1000 Got pros: Compared to version 2: - We took into account all the shortcomings of the second version, there are more functions even compared to the stitched second version. - Touch screen, which made it possible to plug in more functions. - The interface is clear. - Ability to read short messages. - The price is just as good. Different cons: Didn't find it. It really took 2 hours and 20 minutes to charge from scratch, with a battery capacity of 220 mAh, but these are trifles, the charge will hold for about a week.
