    Fitbit lights came on but would not synch with the program. Returned item and attempted to purchase next level up to heart monitor, but correct size not available in your stores.

    I purchased 2 Fitbit Flex's and they were great to begin with. Within 2 weeks we had issues with the charger on one and then a week later the second unit refused to charge. Customer support only tells you to reset your computer and blames everything on the computer. Funny thing is that i never charged it from the computer.
