Lightweight, easy to wear, bluetooth updates all make this a great product. Sleep tracking and constantly updated calorie burn are fabulous. The food logging options seem created for an obese drive-through eater rather than an exercise and health focussed individual. There are NO options pre-loaded for basic health foods like egg white omelet or steamed vegetables. Only options in here are for restaurants I've never heard of, take out places, fried foods, chain food meals, etc. It's mostly useless unless you want to input every ingredient of what you eat. Whole food, whole brand, organic, healthy brands that the healthy eating, workout community are familiar with will not be found here. Also, other brands seem to have these options and also allow you to upload photos of your meals or have photos to choose from as options, which makes it more visual and easy to use. Readout of lights is fun, but I don't know what most of them mean. Manual is online and doesn't seem to list what many of the light patterns mean. Calories are grossly exaggerated, burn says I used almost 1600 a day. I burn closer to 1125 without exercise. Huge sway. It says it learns your burn over time with exercise, so I'll see how this goes. So far... I think I might return and try one of the other options out there. The reason I tried this one was I liked the instant updated bluetooth but that's not as important as ease of use and quality of software.

The device is supposed to be waterproof but within the first day had water trapped under the light bar, a place that cannot be opened up. There were several software issues as well where the data was not being calculated rigth at all. The idea is great for this but it just wouldn't work and ended up returned. I would have tried a second device but the manufacturer's tech support took way too long to get back to me only to give inaccurate information as if they never read my notes to them; then this happened again after I replied and clarified. Weeks went by and I had no fix-- thus the return. I hope they can make this device and program work down the road. I wouldn't buy another one until then.

          I'm not very tech-y so maybe you won't agree with my review, but I LOVE my fitbit. I work a lot and don't have a ton of time for working out right now ( especially since I also have a 9 month old). The fitbit allows me to at the very least attempt to get my 10,000 steps in daily plus I have found that I am makin choices to increase my activity since I got the fitbit.

          Easy to use-like the sleep tracking function and alarm- highly recommend this!

          I use the Fitbit Flex to track my activity. It sure does keep one aware of how much one is or is not moving.
          It shows calories expended (out) and linked with My Fitness Pal, it shows calories in.
          Awareness of activity and food eaten is the first step toward weight control.

          I had the Fitbit Force and loved it. Recall, went to Flex, VERY disappointing. With Force, I have watch, visual results, which push me, rather than a silly blinking light that tells me VERY little! Never realized all the data is not available on the wristband. Would never recommend, and hoping the new model is out soon!

          Comments about Fitbit® Flex™ Wireless Activity & Sleep Wristband:

          It does what it's supposed to do well, but it has a major flaw with the tap-to-control method. Vibrations seem to activate responses reserved for tapping, the only method to physically control the device. Specifically, to enter and exit sleep mode, the instructions are to tap repeatedly until the device acknowledges the mode change. However, pushing a shopping cart and riding a bicycle both - and repeatedly - cause the device to enter/exit sleep mode. This makes wearing the device frustrating at times.

          Using for weightloss, but only able to sync with computer. Even though my Note II is listed as a compatible device, I have yet to be able to sync to my phone. Makes for limited access. Also states it should work with My Fitness Pal app, but when I try to sync, it requests I buy one. Not the best thing I've bought. Probably should have stuck with my Polar.

          Comments about Fitbit® Flex™ Wireless Activity & Sleep Wristband:

          I had to reset my FitBit several times before the silent alarms and goal alerts functioned properly, as each would go off randomly throughout the day. This device does no one thing particularly well, it just does a myriad of things and it's the least obtrusive among its competitors. If you're trying to change your lifestyle from being sedentary to being active, this is probably more appealing. If you want to accurately gauge your caloric burn rate, daily steps, active time, etc. look elsewhere.

            With limited time to work out, fitbit motivates me to park far from the buildings I enter throughout the day. I take the stairs instead of the elevator. This has helped me keep weight off, even though my work out routine has become more limited due to work schedule. My wife, friends, and I enjoy the friendly step # competition.
