    Thus product quickly helped me realize that I was not walking as much as I thought. So I found ways to slightly increase until I was consistantly meeting the goal. It's a great basic tracker for everyday life to see how active you really are.

    I like the flex band for its simple use. Just strap it on and go. No buttons to push for stopping and starting. I also like the sleep mode and the fact it measures your restlessness throughout the night. A good night's sleep contributes to weight loss and mental well being. The only thing I do not like is its monitoring movement constantly so removing it during activities such as showering and hair drying is a must. I also understand it measures rocking in a chair. I will definitely recommend its use for all individuals looking to measure activity.

    This is a cool gadget for the fitness buff. My wife bought this to help keep her accountable for her fitness routine. The instructions seemed to be lacking a little, but the setup was pretty easy. Wife seems to enjoy wearing it.

    Great product but annoying latch

    This is a lot of fun and is motivating me to walk more. I'm disappointed in the latch though - surely with all those brains designing fancy technology they could figure out a latch that is easier to snap and less likely to unsnap

    Love, love this toy! Don't know that it's totally accurate as it tallies, but it's close enough for me, and it absolutely gives me a fair daily and weekly comparison of my activities and nightly sleep habits. I wear it 24/7 (except when showering), and I guess I'll have to remove it when I start swimming next month--oh well. Small compromise, given that it has removed me from counting calories, wearing a pedometer, counting food points, or wondering why I'm so tired during the day. The plastic band doesn't hold up well. Six months is their max life span, and replacements are pricey. I found a friend who only uses the larger size (it comes with a lg and a sm), and I exchanged my large for her small.

    A friend talked me into getting this and I actually really ended up loving it. It's been 3 months and zero problems. It works great with the app and pretty user friendly. Anything I couldn't figure out, the forums easily answered.

    The Fitbit is an easy to use device that tracks sleep patterns along with the number of steps and calories you burn in a day. I wear this device all the time. It's also waterproof, which is great.

    I would highly recommend this product as it was very easy to set up and use right away. My girlfriend uses it every day and tracks for steps with ease. It gives her peace of mind knowing that she's moving around at such a paste each day.

    Bought this as a gift for someone. They wear everyday and really get a lot of productive feedback. A great tool for staying motivated to increase your daily activity levels. Sleep tracking is also a cool feature. Just put your flex in sleeping mode and check the next morning to see your sleep patterns.

    Honestly, I have enjoyed my fitbit. I have enjoyed setting goals for myself and it has been eye opening the lack of sleep that I get. Also, the menu when logging food is extensive and I appreciate that as well. Overall, I think it is easy to use and pretty worthwhile purchase in helping me track and stay motivated.

    My gf loves her Fitbit and never takes it off. So far so good as far as tracking steps. She still hasn't been able to get the sleep tracker to work correctly but is working on that. :) Great gift for anyone looking to get healthy.

    I love it. So easy to use, comfortable, and goes with anything. Only problem is that sometimes when I would wake up in the morning, before even taking my first step, my log would say that I had already taken around 70 steps.

    Works pile it should. Only downside I've found is the band isn't attached very well to the plastic piece. After taking the out the unit from the band to charge it several times, it seperated. I glued kt back together, no biggie.

    This FitBit Flex is a replacement for one I"ve had for a couple of years. It wouldn't hold a charge for very long any more (as with any rechargeable battery-operated device). I use the FitBit and the iPhone App to track my walking, exercise, calorie intake and sleep cycles on a dialy basis! Easy to use!!

    I saw my son had this band and his wrist (provided by his company). He explained all that it did. I received one for Father's day which was great as I was heading to Disney World. First day at EPCOT logged 9.3 miles and over 20K steps. It allows you to set goals for steps, miles, calories, water intake, food intake etc. Now it helps me be motivated to make most of my daily goals - 10K and 5 miles daily. Plus I make sure I drink the water I should. You can also join your friends and family to see how they are doing as well. Have to recharge every 4-5 days, but this can be done while you are sleeping (unless you wear it to bed). Also, it is water resistant so you can swim or shower with it.

    Got the black for myself and liked it so much my wife got the pink one for her. This is a great way to keep track of your activity for the day and push yourself to hit your daily steps goal. Prefer this over a normal pedometer because it's easier to wear this on your wrist than clipping on one your belt.

    Tracks steps and sleep. If you eat out a lot the food diary has lots of food choices. Battery only needs charging about every 3 to 4 days.

    Gave this item to my daughter-in-law for Christmas. She loves it and wears it all day. She is more aware of how sidentary she was and is trying to move more. It gives all the important information regarding your movements during the waking hours. No problems connecting with her iphone and using the app.

    Previously bought Jawbone UP. Failed fairly quickly. Switched to Fitbit Flex. Now the family owns 3 of these. Don't expect perfection to the step and mile, but is consistent for me and a good motivator to increase my activity level.
