The battery lost charge as soon as it disconnect from the computer

Put it on the next day, before I even get to the gym it went off, battery lost charge

Please double check the computer app status before unplugging!- big enough to easily see the display/time, but small and light enough that you don't feel like you're wearing a computerJust realized that I did have 1 con in mind: proprietary charging dock

Love this watch - was able to grab gps right away in Folsom, CA (for the California International Marathon) however, after charging fully the night before, but it lost charge at mile 18.

Inadequate instructions, USB charging cord with no ac adaptor, doesn't do what I expected.

Not happy to say the least, but connected again and at second disconnect the frozen charging screen was gone

sites.the battery drains quickly... has to be charged every day, even if turned off.

:) Works just as i have expected, really awesome buy :):)
