I LOVE this band! I had the Fitbit One (clip) for 3 years….its been washed, went swimming, left in dressing rooms, you name it. I’m honestly surprised I didn’t lose it sooner. While I loved the simplicity of the One, when I finally lost it the Flex 2 is the same price so I figured I’d try to make the switch…..I was nervous about a wrist tracker from stories about grossly inaccurate step counts. I have a very small wrist and found this to be thinner on my wrist than my Michael Kors watch. It is extremely lightweight, and simple. If you are “gadgety” and want more of a watch function, this won’t be it for you. All it does is with 2 quick taps shows your progress on the buttons during the day. It will vibrate with calls and texts, and can remind you to move your 250 steps an hour. It has done a good job with sleep tracking, and I must say is pretty accurate with the step count.

Great all-around device!

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.

Great product for a reasonable price

Easy to use, looks great, awesome features including tracking your run through your phone’s gps. Only real downside is it tends to eat through the battery. Not a deal breaker, but I could do with it lasting longer then 3 days – this is based on tracking at least a 5k run per day. I have lost a lot of weight but I need to maintain it so I use 

LOVE this FIT BIT FLEX 2 (SWIMBIT – as I call it) so many great features)

LOVE my SWIM BIT! (Pat pending on that name!) HA HA ~ We live on a lake as does my sis, plus we ocean swim on vacay so…I was never getting credit for swimming! I am part mermaid! I This is FAB!!! I love almost everything about it ~ The fastener was not as secure, acc to reviews, I had read (due diligence before purchasing while comparison shopping) but that was easily solved by an additional purchase of the silicone fitness bands (in another review (those came with a buckle and found a ten pack of awesome colors ~ prob more than solved) I love how it is wearable in the shower, has “get active” prompts and when I had cell reception but was in a noisy restaurant and didn’t hear my cell phone, my fitbit vibrated that I had an incoming call (so Super Spy cool!) it was handy because we were meeting folks and a busy street fair was going on outside (hence the noise) it also tracks sleep and still works my iphone (like my fitbit Zip did) FAB!!! LOVE this new purchase! So much more comfortable than a waist pedometer ~ super happy with this purchase!

Worth the money – would recommend

I love this Fitbit, I really do. This is my first time purchasing a Fitbit product and it was well worth the money. I’ve been wearing it for about a week now and I’ve tested the accuracy of the step counter countless times and it has been spot on nearly every time. It really does automatically track your sleep and automatically notice when you begin a workout. That is what makes it so great to me.

So thin and descreet! Love it

Love this fitbit! So thin! I wear it alongside my 38 mm apple watch and it is awesome. Doesn’t look weird, just like having a thin, descreet bracelet. Highly recommend. Love my apple watch, but will never leave fitbit because of the challenges and how well the app works for my gps workouts!

Very happy

I’ve owned several Fitbit devices with the HR feature, but I decided to buy an Apple Watch so I didn’t need them anymore. So I thought..after only a week I really missed the Fitbit features and decided on the flex 2 so I could wear it on the same wrist as my watch. The lights will light when you reach so many steps throughout the day. You can also get phone and text notifications. I don’t use those features so I have those 2 turned off. I use the alarm feature to wake me up in the am and to remind me it’s time to clock in at work. It tracks sleep…I honestly don’t think any of them are very good at sleep tracking..but that’s my opinion. I love the fact that it’s waterproof and I can wear it in the shower. I never take it off but to charge it. All of the other Fitbits I owned (charge Hr and the blaze) the bands gave me a rash and I had to take them off frequently. The flex 2 hasn’t done that yet. Not sure if it’s because of the thinner band or why. I love how thin the band is. I don’t have a problem putting it on or taking it off. I ordered a 3 pack of different color bands directly from their website to change them out. Overall..if you don’t need the hr feature, stairs climbed and don’t need to know the exact count of your steps without looking on the app this is a great option.

Should have a better battery life.

I got this to replace a defective Jawbone UP2. I’ve had it about 2 months and so far, I like it fine. I like the petite profile of the band, it mixes in nicely with my jewelry. I like that there are options to get bangles to use instead of the standard band.

Highly recommend for you swimmers!!! Of course for runners too!

Ok, I am a longtime Fitbit user and was hoping the Fitbit2 would be a quantum improvement on an otherwise great product. After using it for a few weeks I can say that it certainly is.
