Отзыв о 💪 GSMIN G20 Smart Bracelet - 2020 Edition (Black) от Bhavin Patel ᠌

The product is greatly overestimated - the device copes frankly badly with many of the declared functions. In general, the company needs to refine this device for a long time and hard. Has pros: 1) Comfortably sits on the hand. 2) Measures pressure quite well, although it systematically underestimates the value. 3) Measures (or attempts) a lot of reasonably useful parameters. Cons below: 1) The heart rate monitor works well only without loads. When running, it very often overestimates the value (compared with manual measurement). With a real heart rate of about 140, it showed 150. Once the readings just got stuck at 180 - at least accelerate, at least take a step, it still thinks that 180. Only restarting the running mode helped, and then only for a while. 2) Also, in the running mode, once it began to spontaneously exit it, as if someone pressed the control buttons. The problem was solved by itself on arrival home after a while. 3) The battery life is about two to three days, and even less at near-zero temperatures outside the window. 4) Poor quality translation of the application. In most cases, it is clear what they want to say. But it is possible, and easy, to do much better. 5) Incorrect sleep monitoring - sometimes the sleep time for two days adds up to one. If such a simple problem is found, then surely there are many others in more complex algorithms.
