Below you will read a summary of them:

  • I loved my One and this one is even better. It is so light and thin and counts really well. It will give you a vibrate when you get notifications to let you know to check your phone. Does well with the sleep tracking and constantly reminds me to move. You won’t regret buying it.
  • My other one lasted a couple years before the charge went out. I use the app on my Galaxy and it works well. It lasts about 4 days on a charge and gives me just what I need. They do have more advanced Fitbits but I like the basics with a little extra. Nothing complicated. I love the simplicity and design of this one.
  • It is so easy to set up. They made the app so easy to use. I am tiny so this works great on my wrist. I like that I have to look at the a to get the info so I am not constantly looking at my wrist. I just wait till the end of the day and compare notes. It is great.
  • It’s like a swatch watch but better. You can change the bands out with a plethora of colors. And the tracking is spot on. I like the style and simplicity of this one and it really makes it easy to maintain a more healthy lifestyle.
  • It is so thin I am able to wear it with my Apple watch no issue. The reason I still wear the fitbit is because it is fun and challenges you. It has a community and is way easier and less technical than the Apple. The app is great and works well with the GPS. I really love this thing.
  • So easy to configure to your daily routine and what you are looking for. It allows you to scan food and make sure your doing yourself right. I have lost 4 lbs since I started wearing it and it keeps me moving all day. It is amazing what this little sinny wrist thing can help you with in life. I am impressed and highly recommend it.
  • Super user friendly device and app. It actually has features I do not really use. It is small and fits secure. I really enjoy the sleep tracker. It is wild how much you can tell about your health based off sleep. It tracks my steps great. Thanks Fitbit. I love this thing.
  • I’m basic and do basic stuff and this is pretty basic on the tracker level and I like that. I don't do any crazy athletics. I am just simple and like to keep track of my body now that I can. It does a accurate job and is super easy to use and set up. Seriously, it is a nice little piece of equipment and is helping lose weight without heading to the gym. It also has a good charge on it, like 2x a week. Better if it was one, but splitting hairs.
  • I am a fan. This is my first tracker. I am able to wear it n the shower without worrying about water damage. I can link it to the app on my comp and my phone super easy. It fits my small wrist really well. It has a good vibrating alarm, which is great in the mornings. I like the light show for getting me motivated for my 10,000 steps. It charges easy and last a good while. I mean 4 days max. I am super happy with it.
  • I ended up buying this even though i have a Apple watch. It is just so fun and looks good. They have a great community and Fitbit has a lock on the best way to motivate and track. There whole system and app is well thought out. I feel like I have a personal trainer on my wrist, when it comes to motivation.
  • Really accurate little motivator and tracer. I like the sleep tracker a lot. It is so easy to use, I love simplicity. That is also set in the design, really simple. I love the buzz alarm, no more treacherous noise in the morning to wake me up. Way more relaxing. It charges really quick and lasts a few day. Really great product.
  • I had the one for years and it was really dependable. I upgraded and am not disappointed. Its been through the washer among other things and it is fine. I love Fitbit, and already had a Fitbit One when I purchased the Flex 2. The One I have had for several years & it's been very dependable. I have even accidentally washed it in my It tracks swimming, no issues. It helps me get to moving. I had back surgery so I get stuck and this helps. I like that is notifies me when I get messages. Only time it is off of me is when it is charging. Both my fitbits link to the same account so I can wear the other when it is charging. I really recommend this, it is great.
  • This is so great! I love it and think everyone should own one. It tracks flawlessly and the app is so easy to use. It offers a lot more than I was expecting: sleep, stairs, swimming. I mean seriously it is so small and unique nd interchangeable with the bands. I really enjoy it. If you are super active get the band and not the snap one though in case it grabs something.
  • I can take this deeper in water, like the pool, than I was able to with the One. They are so simpel to get up and running. I am able to use both my Fitbits on the same account. So convenient when one is charging. I really like the Fitbit community and their products. I am super happy with it.
  • I like the little LED lights- one light equals 2k steps. It is a really nice sleek design and is not bulky at allt doesn't stand out when i am wearing nice clothes. Just looks like a bracelet. I can change the colors. It tracks really accurate. I feel what makes Fitbit so great is they really have listened to the community over the years. It is pretty amazing how well this does and helps. The Bluetooth is about 30 feet, which I find impressive. Great little device.
  • it is most definitely an upgrade. For starters, the battery lasts a whole lot longer. I love getting my red dots so I am a superfan of the reminder if you haven't gotten the 250 steps in. I have been using it for 0ver 6 months now and I have lost about 30 lbs. Meeting the goals I set step wise have been a real lifesaver. It has changed my life. I love it.)
  • The most battery pull is the syncing with the phone. It lasts about 3 days though, way better than the last one. I was bummed it does not connect with the S9 either. It worked great with the Apple phone. I really love this device. However, not that I have the S9 I will have to find something else.
  • This is a machine calculates so well and helps you really stay motivated. I am so hype on this thing. The accuracy and simplicity is so wonderful. I really cannot find an issue honestly. I was super impressed that I could take it swimming and it actually tracks. I haven't found one yet that does that. I mean it is so tiny and slick.
  • I bought this just because it looked so cool. I love it.I have two other fitbits that I use as well. This one is great when you want to go out. I like the fact I can change the bands. I am able to connect all my Fitbits to my account. SO I never miss a beat. It literally picks up where the other left off. Fitbit is the best and this 2 is killer and looks great and feels secure. I ended up buying them for the whole family. We like to challenge one another. The notifications are not he best but I have other ones for that.
  • The only thing that i disliked about this is the fact it does not count stairs. I wish they would give you a better count too on the app. However, the device is really well designed and works well. It is really basic with a few extra perks compared to the one, like a onger battery. Fitbit is great too, mine broke and they sent me a new one right away, it was just a clip but they did a good fast job of helping me.
  • I moved to the Flex for the swimming option. I miss my Force. This is horribly inaccurate. I am apparently now only doing 1000 steps daily. I am disappointed.
  • I liked this thing at first. It was accurate ad was small and fit well. Then it started to fail. Counts went down and were very inaccurate. The ap is not good at all and I do not like that I cannot see my steps on the wrist. It is confusing to put back on after a charge. I am not liking it at all. Waste of money.
  • This stopped syncing after a few months. Then, it just stopped working all together. It won’t charge anymore. When the syncing stopped it would also erase all the info. I feel robbed.
  • I have had 4 previous Fitbits and I loved them. This one though is so inaccurate. Painfully inaccurate. Sometimes it will lose sync and lose the info as well so this makes it useless. I am bummed about this for sure.
  • The strap disintegrated after 6 months and allowed water to get in and it was destroyed. Obviously these are not made to last. That is all I have to say about that. It is supposed to be waterproof.
  • This died the second day I had it. Tried to charge it and reboot it and nothing worked. I tried again and it erased all the info and died. I sent it back. I'll try something else.
  • I would warn against buying this. I had one die after a month and when I received the new one it was used and wouldn’t sync. I was overy bummed. Then they wanted to argue with me about the refund. So annoying.
  • I wanted something to go in the pool with and count laps. Well, it didn't track at all. I figured it was a fail on me since it was counting steps. However, after a couple months it just dide and won't charge back up. I am not impressed at all and want my money back.
  • The pod fell out. I replaced it and after a few months it fell out again and it was lost. I am so disappointed. I liked it while it worked. I am not sure why this is happening. Not something I have read about much.
  • This is a whole lot of NOPE. The band started to fray after a few wears and it is so inaccurate. This is nothing compared to my Jawbone. I feel like its an estimator.I can do that on my own. It took my nail filing as steps. So I assume any time I move my arm it is counting. Totally bogus.
