1. If the start and finish are in the same place, and you have track guidance running, then it may happen that after the start you immediately finish. The biggest flaw of this watch could be to make a logical protection so that the finish does not work a minute after the start. Previously, it was necessary to restart the activity, now only to restart the tracking on the track, although this has been corrected. There is a function to start the track from the beginning of the route, but there is a nuance that if the organizers set the starting point of the route 30 meters from the starting point, then in order to start guiding along the track, you first need to get to this point. In general, as long as you're lucky, you may have to restart guidance on it on the route.
2. There can be a maximum of 4 fields in training, sometimes I would like 5.
3. It is sometimes inconvenient to read notifications that come from a mobile phone, if you didn’t read it right away, then you need to pull it out with a touchscreen that works every other time, it would be better if this function was activated with a button. Synchronization and notifications work fine, here they write about such jambs without apparently understanding it.
4. Since there is no map in the watch, it would be great if you could put waypoints in it.
5. When the screen is locked during training, the screen is completely blocked, you can not scroll between other screens while protecting the watch from accidental pressing and stopping during activity recording. For example, when using sticks, you can accidentally press a button and stop the activity, there is a lock for this, and so, in order to go to another screen, for example, from a pulse to a track, you will have to unlock the watch. These are all nuances that most buyers will never get to, but athletes use it and I can compare it with the convenience on other similar gadgets.
