:grincry:The 10 update yesterday morning totally put the screw on the sync with the puter when the usb charger is hooked to it. The good news is that after a factory reset and sending the Bands SN# the thing works even better with Bluetooth. Don't figure, but the charger works when hooked to it and Bluetooth updates to the puter and to the phone. My bet is The BAnd it won't last the year. But cross finger still. It is charging right now and pushed form 60% to 80% in 1/2 hour. Do I have the patience to wait an hour to get 100% power. I will have a hard time making my calorie qu0ta if so.
