Once Fitbit was taken over by Google, the customer service has become appalling. You will be held online for hours by support personnel outsourced to non-English speaking countries, with ridiculous requests like asking you to take videos of what the watch is doing (when the display will not light at all). After this, you are required to mail the unit back to them, and so far, 4 weeks later, I have gotten no replacement on a watch that was 3 months old.
