The FLEX is ok for just basic purposes but don't overlook the Charge HR for only a few dollars more it is worth the investment to track more. The biggest problem with the Flex is that to track sleep you have to manually start the sleep mode.

We bought for our teenage son. He had been wanting to compete with us and several of our friends in challenges. Let's just say, he kicks our butts most weeks! It has been a great motivational tool to get him of the video games so much and out doing more.

I enjoy the FitBit Flex better than the FitBit One because it will not get lost (my FitBit One fell out of the holder) and is easier to wear at the gym.

Overall great. I loved the display of the ONE, but this is better for my husband. He has been able to NOT loose this one (so far) and he actually uses his to track sleep since it is already on his wrist.

Great product for those who wants to lose some weight. I got it and already lost 10 lbs in a month. Just make sure you enter all the food items in the app to know the calorie intake and drink plenty of water and always meet the goal steps and active minutes everyday.

I've only used it's for two weeks - a bit concerned about misplacing the charging cable - have worn it in the hot tub by accident a couple of times with no adverse effects, but they caution you not to do so ...

The Fitbit motivates me to try to exceed 10000 steps per day to burn more calories.

I am in love with my Fitbit. It is awesome to see how many miles I've walked a day and how well I sleep. It also is good with helping watching what you eat. I would definitely recommend th Fitbit.

When my first FitBit worked, I really liked the tracking, smart phone features, and ease of use/ware. The first one's battery quit working so FitBit promptly sent a new one and this one works fine

I had a fit bit one which I really liked because of the readout on the device. But because it's clip on I knew it would be too easy to forget it at home or lose it. So since the app is the same I returned it for the Flex w the wristband. The dots readout is up satisfying after the readouts on the One. But frankly since the readouts on the app are the same it's fine since I always have my iPhone. It vastly overestimates the steps so You just need to know that. And the sleep tracker is very inaccurate. One night I was up 4 times to go to the bathroom, and in the morning the app incorrectly said I was up only 1 time, and restless 6 times. For me, it's a nice helpful tool but far from accurate.

a great way to motivate if you're stuck in a rut. Friend your friends and cheer or jeer them. Although its common to have to replace it because it stops working, I'd recommend keeping the receipt.
