Now the BUT and the reason of only 3 stars. After not quite 3 months (Ordered end December 2014) my band says from now on equal no sound more. It seems to work because data is sent to the app but the display will show, if at all, only briefly, any wild characters and dashes. All try the tape "reset" but failed, so today I contacted Garmin hoping to exchange.
So on a good device that does what it should, when functioning. In this respect a return also out of the question. I'll keep you informed ...
Update:
So the return on Garmin itself was fairly straightforward if you take it apart, that the postage is payable itself. That should be safe elsewhere similar and this one has the equipment ordered happens to the net and not brought from the merchants.
Garmin exchanged the device without difficulty. With 5 days later I held a new Vivo Smart in his hands, which works flawlessly so far.
With the Bluetooth connection, there is at least the iPhone no problems. If one has once too far, the band takes on approach again also quickly connect. Only for drivers with hands-free, I recommend to disconnect the tape. My connection of the VW speakerphone (ex works) sounds a little odd in the compound when the tape is connected at the same time.
Otherwise there for problem-free exchange of Garmin adds one star.
