    I would have given it five stars except twice it has popped off my wrist without me noticing and fortunately I found it. For the cost, I would like a more secure closure on the wristband. Pros - battery life is awesome, tracking and messaging with friends is fun, weight loss tracking feature is great too. Con - risk of falling off and losing it.

    I like the sleep recording as it lets me know how much sleep I'm really getting and the quality. The best feature is the silent alarm. No more waking my partner with my alarm clock!!

    I purchased 3 Fitbit Flexes, one for me, one for my daughter and one my mom. We all love them and they are still going! They are the basic model but I am able to log into my computer, or smartphone to see progress. It tracks my steps, exercise and sleep. I could also track food from the webpage but I do not use that feature. It will track well when placed in my pocket and I love that. I am very pleased with my Flex!

    When I was looking at fitness bands it came down to the flexbit flex and the up. For the price the flex gives you all the same functionality of the up24 for cheaper. It's very comfortable and most times I don't even notice that I have it on. The app is very in depth, I use it for the sleep tracking and it is very in depth as far as how many times you woke up and how long you were awake each time. The monthly summary email is a very nice touch too.

    Love my fitbit- not as big and bulky as others and so many different band colors a=to choose from Did purchase a band with a watch clasp as the one it comes seems to come off easily.

    It helps keep walking to reach the goals. Easy to set up and good connection. It's a pity that it cannot export data to iPhone.

    It's nice because you can change out your band. When paired with the for bit app on your phone its just as good as a charge.

    I like the fact that you can change bands to match your wardrobe or mood. Very durable! I wore mine while installing a chain link fence, and it took quite a beating without any damage.

    I loved my FitBit and had used it to track my steps and sleep. It is a great tool to use if you want to analyze your activities verses food consumed. Several of my friends have one too. The sad part is it broke yesterday and will not synch. I purchased the Best Buy two year warranty so I am taking it back tomorrow. I am hoping it isn't a trend!
