    Lots of pros such as comfort, design and features. Totally love that it's water/sweat proof, and the slim design makes it more discrete than other models.

    It is a great value for what we needed. We were looking to count steps and see how we were sleeping. It was inexpensive and very easy to set up and use.

    Just the tracker I needed for activity and sleep tracking. Love that it is waterproof, and that you see that there is a text / call on your phone. Sleek and unobtrusive. I love that you can also wear in other type of accessories for going out, in the office, etc. and not look like you're wearing a fitness band. Purchased as a replacement for a lost Jawbone UP2 with the skinnier bands.

    I have enjoyed the Fitbit Flex 2 Activity Tracker. I was looking for something simple with a lower price point. I wanted to track my steps, sleep, and water intake and it has worked great. It can also track exercise, calorie intake, you can set alerts and reminders and more. I have been very pleased with this device, the ease of use and detail of the app.

    This fit bit was a perfect choice for me because I'm not interested in having another watch or one that does all sorts of fancy things. I just wanted a device that would accurately track my steps and give me a good indication as to my sleep cycle . It is waterproof and I can wear it while swimming or taking a shower . I can choose to wear the band around my arm or my leg.

    This is a great little fitness tracker if you looking for something very simple without all the bells and whistles. I wear a watch and didn't want a fitness tracker that also functioned as a smart phone. This tracker is great if you want something to track steps, sleep and remind you to move. Doesn't do much else but that's all I wanted.

    The Fitbit flex 2 is a great activity tracker as well as a sleep tracker. The fit bit program available on the IOS and Android phone platform allow you to be super competitive with friends and other individuals using the fit bit trackers. The battery life for me would be a few days. It states up to 5 days in the instructions. The fit bit will vibrate for incoming text notifications as well as incoming calls. The tracker is water proof and the band seems to be constructed of durable materials. Over all I would recommend the fit bit flex 2.

    I upgraded to this from the flex. Things i love about this new one - the band is more secure and I no longer have to worry about this falling off my hand. This has a much sleeker and modern design. It tracks sleep automatically. It also gives you the ability to have message and call notifications from a very affordable device.

    Bought for my husband who has lots of watches so the basic tracker made sense. Works through app on iphone counting steps, setting goals, tracking sleep among other features. Small device comes with two adjustable bands. He loves it. The watch version has more features and makes more sense if you want a watch that does more.

    I wear a watch every day, so didn't want/need a fitness tracker that tells time. The Fitbit Flex 2 is compact and light on the wrist, yet has great features and is amazing for its size, and-it's waterproof! The App is simple to use and motivates you. Love the Calorie in and out and the sleep tracker..... all in all, a great device at a wonderful price!

    I did my research before going ahead and buying the Fitbit flex 2. I chose it because you can swim with it, no problem. I absolutely love that feature and also love how small and comfortable it is on the wrist. My only issue with the flex 2 it that there is no heart rate monitor. If this device had this feature it would be absolutely perfect.

    Looked at all the fitbits, and decided the smaller the better for me. All I wanted was something to track my daily steps and keep me motivated. The app is perfect and the fitbit does exactly what I hoped. Small and discreet yet gets the job done. Battery life isn't crazy but I don't sleep with it on so charging is no problem.

    It is definitely water proof because I wore it in a foam run and wore it to the water park consistently over the summer. It does loose its charge pretty quickly. I had to charge this one once a day compared to my Blaze that I only have to charge once or twice at most a week. For the price and the purpose it is great!

    Great for water exercise. It's waterproof!

    GREAT for my pool time exercise. Waterproof is what was needed for my exercise tracking. I have arthritis and find water exercise is what works best for me. I do pool walking and some laps almost daily. I tried it with my water dumbbells, and I didn't get credit using the dumbbells while standing still. So moving is what it takes with arms and legs. It may not be 100% perfect, but it gives me some credit. I love the sleep tracker. I like also that it reminds me to get up and move if I find myself being lazy. Good motivator! I have been very happy with this fitness tracker. Although you have to have your phone, tablet or a computer nearby to see your accomplishments it's not a burden since most of us have our phones glued to us anyway or a Tablet handy. I wish I didn't have to manually add my calories eaten for the day or each meal. Overall I love my Fitbit Flex 2. Hope they get more variation of colored bands available retail in small and LARGE. Thank You Fitbit for the waterproof band. Negative points: No AC adapter included. I have one with my android phone, but nervous about using it. So have to plug into computer to charge.

    I love this simple tracker as I’m not the greatest with technology but I found it easy to sync to my iPhone. I love that’s it’s waterproof as I canoe in the summer, farm, and swim in the gym. My only suggestions? Heart rate tracker and more colors of bands to purchase to match outfits. Overall great product!
