    The Flex is much better than the Zip version of Fitbit (which died for no known reason after a few months), but I keep waiting for a product from this company that'll easily deliver everything promised in the models. Set up took days; Fitbit tech support didn't respond to my requests for help until 3 days after I wrote (note: there's no one to speak to live). After start up glitches were resolved, there were numerous communications from them that asked the same questions 4 times. I've had other questions about this product's performance but it doesn't seem worth going through additional disorganized customer service with these guys.

    I planned on buying this months ago when I first found out about it but was quickly disapointed... one band was too tight and the other band fit but easily caught on things.
