Without running the activity:
When walking on a plane without letting go of the activity, the floors or height start up. At 6-8 km, I can do at least 10 floors on the level.
When starting the activity: (hiking)
It calculates the height incorrectly. At 13km with the other 3 facilities, the height was 458m. According to mapy.cz, the height should have been about 422m.
Venu 3 measured a height of 756m, which is 300m more than should be realistic.
It also beeps annoyingly after each set height meters (floors).
There is a big difference. Every 5 floors will be from 12m to 20m high.
