Does what it says it'll do, tracks your steps, monitors your sleep, and finally they're waterproof so it can also track swimming laps. I like how it has notifications for phone messages and movement reminders that you can opt in and out of. It's light, comfortable and very easy to wear/use solid little fitness friend. Down side is with certain settings it has a very short battery life, upside is if you set it right the charge last is about 4 days with continued wear. Charging isn't that slow either but it does take around an hour for a full recharge (I tend to charge it at night as tracking my sleep is a secondary use on it for me)

Love that it's not bulky and it looks like a bracelet. I bought some accessories that change it up. Love it! Nice little tracker that keeps me on track...

I bought this device for my wife and she loves it, now she can keep track of all her activities such as; calories burnt, how many steps a day she does and how much sleep she is getting. She gets a digital track of her activities through flex 2. She loves this device and I do too since she can now track everything she does with this device by simply downloading the app on to her phone or computer and by the end of the day she knows what she has done or what she needs to do to keep in track.

I love the reminders that this model provides to motivate you to walk. The fit is amazing and it is very stylish.

Loving the fitbit flex 2! It helps to keep me mindful of my day-to-day activities and how I sleep at night. Worked great right out of the box. Love seeing my activities tracked. Band is comfortable to wear all day and sleep with at night. Super lightweight too. Glad I went with the flex instead of a bigger band like the Alta. Very happy!
