Pretty cool, but not perfect

  • Familiarity: I've used it several times

Ive had this for about 4 months now. I really like that it notifies me when I received notifications from my phone (iPhone). What I dont like is that it doesnt sync with my health data on my iPhone; all the health info it collects it keeps in the fitbit app. I realise this is an issue with Apple not fitbit but it definitely would factor in to my purchase of it.

The battery life is phenomenal I hardly ever charge this bad boy.

I don't leave the house without my Fitbit around my wrist.

Mostly, I use it to track the calories I burn at the gym, but another cool feature of the Fitbit is it tracks your steps. So, you can actually see how much walking you do throughout your work day.

The device is super easy to sync to your smartphone for easy tracking.

Eye Opening

  • Familiarity: I've put it through the wringer

We decided to get the Flex for our kids and my wife has one as well. It has been a great way for the kids to understand how much they are or are not moving during the day. It is awesome to see them interested in how much activity, sleep, water, etc they are getting each day. In fact, having the kids wear the flex has made us more aware of their sleep quality. Something that kids don't often report on themselves. After the first night our older son's sleep data was eye opening. He was having very restless sleep. We had no idea and are very thankful we started using the flex so that we can try to help him improve his sleep quality.

The flex is more basic than other fitbits but it is perfect for our purposes. It does not track floors climbed or monitor heart rate. They are sleek, water resistant, has at least a 5 day battery life, sync easily with the app and seem very accurate.

Also appreciate how it comes with a small and large size band in each box.

Great device, seems pretty accurate, and battery lasts a long time using it pretty much all day long. Operation and setup is very easy, and syncs up to phone and fitness app great.

Simplicity at its best.

I bought this for my mom, who was looking for something between the "yoga DVD's that sit on her shelf, gathering dust" and the "Apple watch." I figured the Fitbit Flex would be a happy medium for her.

While those tech-y watches can be tempting with their multisport and elevation allure, the Fitbit Flex makes tracking your activities pretty dang simple. The slim and sleek look evades the ostentatious watch silhouette and simultaneously offers you versatility with its additional (and rather colorful) band options. The app itself is easy to use and makes adjusting your routines (be it sleeping, eating, or walking) a breeze.

Great product with a great app!

The application is really the best apart about this product it really goes in depth on helping to have a healthy lifestyle. Also has an alarm that is soft enought to not be obnoxious but still enough to wake you up. You get two sizes of wristband with the actual fit bit so these will fit anyone.

Seriously ..

This is the most intuitive little device.

I work two jobs that keep me on my feet and moving. I'm also a vegetarian. I'm also trying to put on weight. I legitimately didn't realize I was under-eating until I snapped one of these on my wrist.

I'm grateful for the application and device itself. It is sleek enough to work with almost any outfit - casual or otherwise. It is intuitive to no end. It is a life-saver.

I've upped my calories, have loads more energy, and am finally seeing gains all because of this device.

Easy to use.

Again, a lifesaver.

Can't recommend enough - if you're trying to loose weight, maintain, gain, anything - the application is extremely simple to use.

Its gentle buzz through its silent alarms are a pleasant way to wake up too .. well, more pleasant than a grating alarm tone.

Great to get you moving!

My husband and I have both used this FitBit. He even upgraded to a fancier version with more features. We got this one for my mom. And she loves to be able to track her steps with this simple, easy to use option. Now, whenever she has the chance to move, she does. It's great!

Great gift

I got my Mom a Fit Bit and she loves it! I keep nagging her to be more active and this is a better strategy than nagging.

Hooked on sleep!

  • Familiarity: I've put it through the wringer

I love my FitBit Flex for the Sleep Tracking Function. I use it religiously, to see what my sleep patterns are ... prompting me to practice better "sleep" behaviors (like NOT glaring at my iPad or iPhone screen for an hour before bed.) I make it a game to see how long it takes me to fall asleep! It's comfortable to wear, and always "rewarding" when it vibrates upon hitting my 10k daily step goal. With regards to Steps, I find that it is inconsistent in picking up my RPMs on my bike (which I don't think it's supposed to count), but is consistent on tracking my paddle strokes when I'm kayaking. I will say that I'm now ready to upgrade to the model with the Heart Rate monitor, as I'm SO ready to get rid of my old school heart rate monitor strap!

Everyone Should Have One

A little pricey but worth it! I wear it all of the time now. It keeps me motivated to stay physically active. Syncs with my smartphone rather well and is easy to use. I like the part of the app where I can add friends and have some competition with all of them.

Father's Day Gift

  • Familiarity: I gave it as a gift but have feedback to share

I got my dad a Fit Bit for Father's Day and he won't take it off (thank goodness!). The wristband is adjustable so it can easily fit anyone. The technical features are great too. My dad being super competitive wants everyone in the family to get one so he can beat us all in the Fit Bit challenge :)
