adidas miCoach Pacer +, Error 810

Hi, I purchased the miCoach Pacer + about two weeks ago and have returned it for a test again. The concept is very good, but unfortunately not mature. How to read in many forums of different communities, the synchronization only works sporadically, always the dreaded 810 error, the USB detection is often faulty, apparently separates the miCoach Manager Pacer to sync to unlock the files, then this often does not Access to more data. Have all variants tried on Vista and Windows7, only with moderate success. I can not mess every time one hour by synchronizing me. The on / off switch is also very shaky and fiddly, have concerns that this would survive this year. Other users also had significant problems with it (canceled).
Conclusion: The system is good (if one disregards from the switch) worked and high quality, nice would be a synchronization option without Internet access. I'll wait to see if Adidas brings out a new version, then I'll try it again, but otherwise I can at this point only advise against it.
