The first one received in Nov, 2013 - placing the bracelet on it goes blue and charges right away (sometimes you have to move it around to various spots before it picks up the device but is
noticeably quicker than the second received charge pad). The second pad received in Jan 2015 takes minutes before recognizing the bracelet if at all. You have to place it randomly on the pad multiple times before (as I said if you're lucky) if sees it - if at all. The one "working" pad goes green when the device is not 100% full.
Making it a
USB charging station only (no adapter plug PS) is a major inconvenience. The wristbands have to be "fiddled" with before they activate on the pads. Not reliable.
My wristband lasts no longer than 48 hours. Its advertised lasting three days (72 hours) but this is not the case.
Mornings after updating/syncing SLEEP data I find is best to recharge the wristband. 2 hours appears to be the time it takes to charge it. Have yet to see it at 100% after the pad says its full (green). Same with the shoe clip Placing on the charge pad shows green led (FULL) and its at 93% according to the android app.
Only one device on the pad can be changed at a time.
