Bests & Worsts Reviews from Amazon

Received the Flex with a low battery level. Didn't think anything about it because of course it would charge. used it for 3 days and the batter was low. Tried to charge it using the included charger and my laptop overnight and nothing happened. Next morning I plugged it in to an AC charger I use to charge my cell phone. Nothing happened. Opened a ticket with Fitbit Support. No response. Sent a second, third and fourth email and still no response after 5 days. WTF? I could see if this was a $10 product but $100? Unacceptable.
