screen that is difficult to see in direct sunlight (only large numbers).
The distance that the pedometer records as being walked before arriving on the bus is considered to be average.
Lack of confidence in the heart rate monitor. It is possible for it to either underestimate or overestimate at times. I'm only able to check things manually, and my estimates are always low. Always be sure you follow the wearing instructions.
There are certain applications that are not compatible with bracelet notifications (Telegram instead of one throws a pile at once, for each unread chat).
No music control (not so critical, there is a headset).
You will need some time to get used to the controls, as they require swipes in addition to the home button, which you frequently press by accident. The thumb should not be used.
Due to the fact that the strap tends to accumulate grime, it is recommended that it be washed on a regular basis (fortunately, rubber). Nevertheless, because it must be removed and reattached on a daily basis, it only has a lifespan of at most one year, and after just half that time, the eyelet on the belt will fall out. As soon as you see a crack in it, place an order for a new one, and if you can, try to get one that is unofficial and made of leather or metal.
When using a stopwatch, there is no feedback, you can forget about it, and the battery will almost certainly die within a short period of time (fun fact: the stopwatch goes to a maximum of 99:59 and does not start again until reset).
Because the charging cable does not always make contact with the capsule, you may need to fiddle with it in order to get the charging process started. In addition, the capsule must be taken out of the device before it can be charged.
The battery has a history of discharging at an unexpectedly rapid rate over time. That could be considered derogatory.
