I'll start with the main one. Batteries hardly last for 2 days (with a minimum of loads: WITHOUT a constant heart rate monitor during training, WITHOUT a constantly on screen and without other things). I don’t even know what to expect if I use the device to the fullest. This is just a disaster, the whole operational life of the device revolves around charging: charging, charging, put on charge, do not forget to remove from charge, you need to charge it in advance, otherwise the alarm clock is set on them, where is the charge, take the charge . Reverse charge from The phone is also not a panacea - surprisingly very long and inconvenient.
Next, about the heart rate monitor. It is extremely difficult to use them in training. I don’t know about others, but in 99% of cases I constantly ask to wipe the sensor. Naturally, I'm sweating, I'm in training! I did not understand what to do with this, so I scored.
The sleep monitor is also kind of stupid, constantly writing to sleep the time of weak activity before falling asleep, as well as the usual lying down after the alarm clock. Today, in his opinion, I slept from 21 to 8 hours. If only, my friend) In my opinion, there are also problems with the accuracy of determining the phases of sleep. At the same time, there is no sleep analytics. Otherwise, working with physical activity comes down to an hourly reminder of the need to move and praise if you were active. It takes a long time to determine the types of activity (in my opinion, it should still take less than 15 minutes to understand that I am on an ellipse, or on a track). In general, such a companion of a healthy lifestyle.
You can set only one alarm clock in one widget, you need more alarm clocks - add a widget for each alarm clock (not needed - delete, in general, experience as many inconveniences as possible). I didn’t see any more useful things for myself, so at the moment for me this watch is an alarm clock and a device for reading notifications / receiving messages about calls when the phone is not in hand.
In the shower, the screen constantly reacts to water. There is an appropriate mode of operation that excludes these reactions, but it must be turned on and off manually. It's easier to just take it off.
