Delivery again very quickly and without any problems, unpacked, downloaded software and synchronized (albeit with minimal problems during the installation process per se, but my also to my computer settings and may have been due rather rudimentary service knowledge ;-)) - and already was the device ready for use.
Have now tested over an extended period (about 6 weeks) the Vifit tracker, where I left the bedroom activities disregard (Tracker has on the included bracelet not really kept well), and I can tell, the device does the job.
We already developed a certain ambition (in my case, 10,000 steps) to achieve its ambitious goal for the day, moves conscious (now I refrain often on escalators and walkways already 'times two stations previously made to achieve more steps), the Vifit discreetly in your pocket always with you, even playing football no problem, the battery will last for several days by loose and is quickly charged via the PC again.
Precise measurement results are of course not reached, but as a rough guide and especially motivation can help the Medisana Vifit Activity Tracker well use.
I am completely satisfied with the device and have it also recommended already in accordance with the family and among friends.
The only "drawback" (if you want to because to call it that): in two days, the Tracker has daytime switched to "sleep mode", which was far too bad, as I've been on these two days lot of walking, this does was not recorded.
However, I'm not sure if this is now just so happened and therefore there is a fault in the device, or if not unconsciously and by chance the control button three seconds (as long as you need to switch to the respective mode) has been pressed, which under certain circumstances even provided once can happen.
However, I respect now enhanced it and check regularly during the day, if the Tracker Vifit actually is in activity mode - since there was nothing to complain about in this regard.
Overall, a useful device as a motivator for more movement and activity in everyday life - I would buy it again at any time.
