    While this wasn't my first Fitbit purchase, I can certainly say it won't be my last. These little fitbits are not only tough but are very accurate. I wear an AppleWatch as well and they both are usually wishing 10 steps of each other by the end of the day. I fed recommend Fitbit if you are looking for a fitness tracker!

    Good product! Helps me keep up my daily activity. Nice size and like the option to switch out bands. Sometimes the tracker picks up steps from other activities and counts them. Also wish the tracker was water proof not just water resistant.

    I really like my fitbit. It is very easy to use as well as to connect to tablets or phones. The app is simple and the networking option allows for you to workout with others without physically meeting others.

    I had a fitbit ultra and loved (and lost) it. The flex is ideal because it stays on my wrist 24/7 and is less likely to end up in the washer. I liked the fitibit ultra's display. The display on the flex can only tell you how far you've gone in 20% intervals. It would've been nice to have a display that showed steps, active time and battery life (especially battery life!). One feature that is missing is the altimeter that records flights of stairs. The flex syncs nicely with the iphone and has a built in silent alarm which is great for reminders (a little weak for heavy sleepers).

    Fitbit has.gaive me the motivation that I lacked for the past few years to start walking and monitoring my progress. I have recommend Fitbit to many friends and more.. Unfortunately, I miss placed my Fitbit and can not find it. I know I have to buy another one, but I do not have the money yet. In short I loved my Fitbit.

    Once you know how to set it up and customize the features, I am really happy with my purchase. You can go to the website for instructions, but I just expected it to come with some. Being anxious to try it out, I did not want to read the novel.

    Got it on sale and with best buy rewards, so even better. Comes with two bands. One big, one small. Easy to use to use and set up. Tracks your sleep, calories, and steps. Charge lasts a few days.

    The inability of seeing my exact # of steps drives me nuts, but I do like it otherwise and it does motivate me to walk more. My fiancé has a Fitbit Surge and we like to challenge each other. I'm thinking about getting Flexes for my parents!

    Pros: Battery- rechargeable, lasts 3-5 days. (I'm an MRI technologist and the magnet ruins most batteries. This one has held up well. Online Syncing- I don't have a computer or phone that syncs automatically, but it does sync via a USB port on my old laptop and I can use the apps to compete with my husband and friends. Water-resistant- I don't have to take it off for showers, etc. Cons: Stairs- This one doesn't track the stairs, some of the others do. Readout- only on app or online after syncing. I can't look at it and tell how I'm doing during the day. I don't know if this is a pro or a con but wearing it on my wrist instead of my pocket doesn't always look the best, but I wear it more because I'm not forgetting it in pockets or on the counter.

    I found that use this product makes you aware of everything you do all day. Walking, running, water and food intake. It let you know how much calories you burned and how much sleep you get and the quality of the sleep. I think this was a great purchase.

    I love my fitbit, but I wish I would have bought the one that had the heart rate monitor. It does track my steps, but I do not know how accurate it is. Also, it seemed to fall off a few times, but the other version would probably be the same

    After researching several pedometer options, the Fit Bit was my choice. I am happy to say that it has been a good investment and works great. Looking forward to designer bands to come out as it would be a nice touch should I buy my wife a Fit Bit.

    The fitbit flex is a great device that allows for fitness tracking of interests such as distance traveled and calories burned. It even allows you to catalog your sleeping habits. There's a useful smartphone app as well as a website where you can view charts and graphs of your daily/weekly/monthly goals. However charging is a pain because you must remove the device from the bracelet, put it in an adapter, plug it into a USB port and then reverse those steps to put everything back together. Overall, it's a nice product that provides a good amount of information.

    This is my second fitbit Flex. The first fell off my wrist one night out. It's small enough to not get in the way with other bracelets I like to wear while also not causing too much of a visual distraction. I don't need a heart monitor, clock or large display but I don't need to be able to track my steps. I'm sold.

    I bought this for my wife and it has really motivated her to get out and be more active. This is a basic step counter, but the Fitbit software is great. The ability to do challenges with others really helps to make one go out and get those few extra steps to meet your goal or to get in the lead on for the challenge.

    Found device to be accurate and comfortable on either wrist. The band clasp flat out sucks. The design is comfortable but I have had the band come unclasped and fall off my wrist 7 times in 2 months. One learns very quickly what actions undo the clasp in less than a heart beat. I charge the device every 3 or 4 days. Wearing the device in the shower has in no way altered its performance. Would like to see the stats that come to me weekly available for downloading into pre-formatted Excel options but this certainly could can be done manually for the enthusiast.
