    I've stayed away from Fitbit (and other fitness trackers) because they were not waterproof. I read about the Flex 2 Fitbit being released and it can be worn while swimming and showering. I wanted one that I would only have to take off to charge once a week or so and this one fits the bill. Good price, very comfortable. The setup with the Fitbit App from the Windows store for Windows 10 was very easy, and my computer bluetooth saw the unit right away. Please note that there are both a small and large band included, but only one of them has the metal clasp for closing the band. If the band you want to use does not have the clasp on it, you have to remove the clasp from the other band and put it on the one you want to use. Very pleased so far. I'm figuring the band will last a year or two but I can always replace the band when needed.

    Basic Fitness Tool To Replace Fibit One

    I used the Fibit One for about 3 years until the battery no longer charged. Bought the Flex 2 right away because I was addicted to knowing how many steps I do in a day. I like the wristband because it's light, thin and I don't really notice it. Nice not having to remember to pick something up and put it in your pocket. Seems to be as accurate as the One as my step count remains consistent between the One and the Flex 2. Two things I wish were better. The Flex 2 needs recharging about every 5 days and the One could last longer. It also takes about 2 hours to recharge the Flex 2 and that seems much longer than the One use to take. In general, I've very pleased with the Flex 2 especially because when I go out walking I always have it on me. I would occasionally forget the One and that was a pain when you are half way through your walk :-(

    Received as a gift. Good basic start. Mainly wanted this for sleep tracking. Would like a little more detail in this area, but it’s okay. If you set the sensitivity to normal, it will tell you you’re getting sleep. I set it to sensitive. Seems I’m pretty restless at night. No wonder I am so tired. Lots of options for keeping track of calories, activity and liquid intake.

    Tracker and Alarm

    I don't really need another step tracker and my phone and watch already do that, but this is a comfortable tracker that can be worn while sleeping for sleep tracking and will vibrate as an alarm. My wife really appreciates this as I get up hours before her and wake up without any audible alarm.

    Holds the Fitbit in tightly and is adjustable for any size wrist. Very comfortable and looks nice. I also wear it on my belt loop or sometimes even my bra strap if I’m doing a lot with my hands. Never had any kind of tracker and this one is very good. The app is really easy and can set up other actity to follow. It does vary from the Apple fit a bit but I like it.

    Got this for myself for my birthday to work toward the next year of getting healthier. Found out how restless I am during sleep hours which may partly explain my tiredness all the time Really helps me with that info and I love that I can set and monitor goals to my own speed. Still learning about some things that I believe will help, but so far, I love my Fit!

    I have been looking at this for a while. Missed the January sale and waited. When they went on sale in may I jumped at it figuring I had the Best Buy 15 day warranty to try it out. I was tracking steps with my phone but it wasn't accurate because I don't always carry my phone. I choose this one because I already had a garmon forerunner for running and didn't need another watch ( maybe when that dies I"ll upgrade) I really like that I can swim in this one and track laps ( I haven't tried this yet) once it gets warm enough for me to swim. I enjoy using it now to track steps/activity, food, and especially sleep! I didn't realize how many times I was "restless" through the night. I am considering getting the metal bracelet in the future with my rewards certificates:) I obviously kept it past my 15 days and enjoy using it daily.

    An excellent buy for the price; as with most fitbits now, it doesn't track stairs. Whether it is the fault of my particular item or the product in general, the promised alert when I haven't done my 250 steps each hour does not work at all. Since I have other ways to monitor this, I am not returning the fitbit at this time, but that is a disappointment.

    The Fitbit flex was a good value. We were looking for a fitness tracker to track steps and sleep for my son. Since those were our priorities, we skipped the ones with the fancy screens, gps, and hr monitors. While it is simpler in its feature set, the result is a very straightforward device that is intuitive and has a long (about 5-6 day) battery life.

    I was looking for a tracker that I was able to wear every day not interfering with my watches. I bought the Flex which I always have on. It's accurate and let's me track my steps, activities, and sleep. I love it!

    This product is not perfect. It has some charging issues that can be annoying. But for the price and just basic tracking it is great. The original fit bits were made better and built to last but these are decent. Wish there were more band color options though.

    This is my 3rd fitbit. I love that you can swim with it. It's thin and has many wear options. Wish it tracked stairs and the battery lasted longer. Compared to my others the battery life is my only complaint.

    This was my first Fitbit device, and I am very pleased with its performance. I had debated getting the Flex 2 or the Alta, but chose the Flex 2 for its slim profile, waterproof design, and lower price point. I have yet to incur water damage, and the five-light design is very minimalist yet informative.

    We purchased this item for my husband, who uses it to track his steps for FSA purposes. If we get 5,000 steps per day for 20 days per month his employer contributes to our FSA. I have a Fitbit Blaze that I use to monitor far more, but if all you want to do is track your steps, this will do the trick.
