Subtle look and feel ; Wireless sync to selected phones ; Good battery life

No altitude sensor for stair tracking ; Sleep tracking hit and miss ; A little expensive

It's certainly not perfect but the Fitbit Flex's simple design strikes a nice balance between looks and functionality and serves as a good motivational tool to keep active.

Cheaper than some of the competition ; Water resistant

No altimeter ; Not much fun on its own ; Not as accurate as other Fitbits

The Fitbit Flex is the first wrist fitness tracker from the maker of the Fitbit Ultra. It’s reasonably-priced, pretty convenient to slot into your life and is water resistant. However, it lacks some key features compared Fitbit’s other trackers and not...

What we discovered after two weeks of fitness tracking is that the Flex is a stylish, attractive recorder of general activity and motion. For people who aren’t already following a consistent, organized, exercise program, yet want to make sure they’re...

Excellent battery life. Accurate. Comfortable, light, stylish. Includes silent vibrating alarm. Interchangeable bands available in several colors. Bluetooth and NFC-enabled wireless syncing to smartphones. Great Web experience.

Limited display of information on device. No altimeter.

For my money, the Fitbit One remains the best activity tracker on the market, and our Editors' Choice. But if you'd prefer to wear a tracker around your wrist, don't hesitate to order a Fitbit Flex.

Light and thin ; Long battery life ; Wireless syncing ; Accurate and consistent

Boring design ; Doesn't tell you what to do with your data ; Hard to put on and take off ; Inputting sleep, food, and activity is a lot of work
