The Inactivity detector works well and helps in everyday office life really, times to stretch his back. The acoustic warning is decent and also interferes with eg in a meeting not.
A pity, I find that the Vívofit the chance does not take to make the pulse of information optionaen sensor more accurate estimate calories. As Activity Tracker cycling or gardening, for example, therefore unsuitable. The bracelet is only a display unit in Kombinatiun with the pulse sensor.
The software connection is Garmin-typical flaky. Tut times, do not even.
Who really do sports and wants to pursue this, is a device like that detects more. To be active but serviceable.
