It started with the first disappointment that the clock / band can be configured and initialized only smartphone (Android or iOS). Despite WP8.1 apps and connectivity to PC / Mac (which I have not figured out what you can actually do with it. In describing I understood that everything would be possible without a smartphone ..
But even with my iPhone 5s I got the tape is not running. The band remained at each update mode (which automatically starts the first time switch) are and that's it. (Where, incidentally, are not supported) Also on an Android device, I had the same result.
The biggest disappointment ended up being the support.
I had to open a help desk and asked at the same time by phone for help.
On the Helpdesk / mail I have to date received no reply (10 days since then) and my telephone request I had a mail with a photo (although there is this state in the manual) and then receive an email after 7 days I unfortunately the tape has to submit.
Adidas I had really not expected.
The band goes back now and feel like I have completely lost this item.
