I run bike or swim almost every day. It is rare that I don't have to restart the app or reboot my computer to get it to work. I have both a 310XT and a Edge 800 and it doesn't work reliably with either one. This piece of junk is seriously making me think about upgrading any of my Garmin products or getting new ones such as Vector 2.
Tonight I have been fighting with it for over an hour. It synced the 800 tonight but it won't sync the 310XT. It tried once and failed but now it won't even try to sync. WHOEVER DESIGNED THIS SHOULD BE FIRED!
