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.

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

My fitbit stopped working in 6 months. Battery life is not as advertised if you use it 10000 steps a day. Mine lasted max 2 days. The design is bulky compared to others I've seen. I'd recommend shopping around other products.

    I got my Fitbit flex after many of my friends did. I love the option to add friends so you can cheer each other on. Because I work in an office, I set a couple of silent alarms to remind me to get up and walk around a couple times a day.

      The real advantage to the Fitbit is that it keeps you constantly aware of your activity levels. I find just having it on my wrist helps me make better choices throughout the day. I've given Fitbit to a friend as a gift and we compare our progress - makes changing bad habits for new, better habits much more fun.

      The band can get uncomfortable at times, especially after it gets wet [like when washing my hands]. I like that it is so light that I sometimes forget I'm wearing it, but I've had the band open on me several times that if I hadn't been looking I would have lost it completely.

              Love the fitbit, and love Brookstone customer service. I've had to exchange it a couple of times because it can get glitchy after a few months. That said, I'd still recommend it wholeheartedly. Tracks steps and syncs really nicely with myfitnesspal free app and website to log food and activity calories. I've lost over 20 lbs since beginning my journey and it's been painless. Fitbit really motivates you to move more. I use it as my alarm clock in the morning and I don't have to wake up my mate at 5 a.m. I've also used it to track sleep, which is quite interesting.
