This is one of the best products I have bought in years! This product pushes me to be active on a daily basis while competing in fun challenges with my friends and ultimately competing against myself for personal bests. I have had this device for nearly a month and I have not missed my 10,000 steps a day yet. I recommend everyone own a Fitbit!!

I have the Fitbit Flex and i have been using it since September 30th . I have to say it has worked so well for me. Firstly let me explain what it can do for regular users:
1. It is stylish pedometer , it can count steps , distance , calories(calculated based on steps)
2. It monitors your sleep activity - you will be surprised to know how many times you are in unrest condition once you wear this device and track your sleep activity
3. You can set step, distance goal challenge with your friends or the Fitbit community groups
4. Once your daily goal is set it will alert you through email or app notification to clock in more steps at milestones for eg " you are only 2500 steps from meeting your daily goal
5. You can program it to wake u up at particular time every day , you can also program it to alarm you for different things (this is one of the best feature )
6. For the conscious calorie counter - Connectivity to myfitness pal, Sparkpeople, Loseit .com thus you can track your calorie intake on those platforms and see how much you need to walk , run or burn to reach your calorie out goal in this way it gives you real time motivation to burn calories
7. Very neat graphic display on the fitbit app and extensive graph features on the website
8 Instanlty syncs to your android, iphone / ipad through bluetooth :infact you can hold your phone in one hand and walk on spot to see the step count increase- i love this seamless integration

What it will not do
1. It will not count floors climbed/how high did u walk? or Altitude, so if you intend to challenge someone on floors climbed all you will get is step count
2. It does not monitor your heart rate, in HIIT cardio and other kinds of training some people do like to know how many calories they burnt but because this device calculates calories based on steps it does not account for your heart rate, how long you were exercising at max heart rate thus you might have worked out till u drop in a 30 minute intense work out session but the device will understate the calories burnt based on steps
3. You are supposed to wear it on your non-dominant hand , thus somewhat inaccurate step calculation for left handed people
4. does not show time (like Flex/ jawbone/ Polar FT )

Battery retention is very good in the first three month , you charge it for half an hour max using usb charger and the device retains charge for 5 days , however i have noticed with time the battery retention has reduced it now requires charging every 4 days

Bought this to monitor my sleep and steps at work! I love it. It is awesome to see what type of activity I do.

This product is great. It even sends me an email when it needs charging and that is a big plus since I always forget to charge my electronics. I also use the Fitbit app on my smartphone and when I see that I am close to my goal I get off the bus a couple of starts earlier to achieve it. You can also pair it with your weight watchers etools if you are a weight watchers member. The only negative is that if you wish to wear bracelets on both arms it can be an issue as well if you have an event where the Fitbit would not be suitable with your outfit. I wish Fitbit would create a body clip on accessory for moments like these.

I have been using this for almost a week and i am liking the motivation it provides. I like the stats at the end of the day and the reminder that i need to move a bit more during the day.
I am not sure how accurate the steps are, as one day i used the treadmill in the morning and gained over 4500 steps, and the next day it only registered 2500 steps for the exact same distance and time. Something that i am going to continue to monitor.
the battery life is good so far.
I wish the bans were more affordable to interchange them.
I wish it was available for my blackberry, but i dont mind not having the instant data. it makes me work harder throughout the day to see my results when i check in at the end of the day on my computer.
I love that it links to myfitnesspal to help track calories and additional exercise.

The Fitbit Flex is awesome. The "Friends" function allows you to check in on your friends' progress and compete remotely. It has definitely encouraged my friends and family to get fit!

Great for someone who runs or walks for exercise. Does not calculate other physical activity like weight lifting however. Therefore not much more useful then an average step counter. If you are serious about your fitness then investing in a quality heart rate fitness tracker would be better.

It's great weather you are looking shed some lbs or just wondering how much you walk on any given day./ I love because it links to my Weight Watchers App and I can calculate my activity points

Got a Fitbit Flex for my birthday (with a pink band - YAY) and I love it! I'm mildly obsessed with checking the app on my phone to see my progress through the day. I find I am actively trying to increase my walking to reach my goals, and wake up each morning and check my sleep patterns. As it turns out, I'm a very restless sleeper. (who knew??)

works great does what i want it to do and i love it has an app!
