The Fitbit Flex fitness wristband, unveiled at CES 2013, is now shipping to the public for $99.95 from the Fitbit online store. The Fitbit Flex comes at a time when wearable activity trackers are all the rage, with Nike and Jawbone also in the space. 

We got our first look at the Fitbit Flex during some hands-on time in Las Vegas. It connects with the Fitbit smartphone app on iOS and Android to record your daily activity over Bluetooth, showing you steps walked, distance travelled, estimated calories burned, and the ability to track sleep. If you want to keep track of calories and what you've eaten, the Fitbit Flex can integrate with MyFitnessPal to do just that. Furthermore, it can wake you from sleep with vibrations. 

As for the band itself, it ships in red, black and green. There are five LED lights to show information as you work to reach fitness goals throughout the day. It attaches to a user's wrist via pre-determined slots for different sizes, which is nice because you won't have to hassle with different fits, like the Jawbone Up. 

The Fitbit Flex is available for $99.95 (£65), slightly cheaper than the $130 and $150 that run for the Jawbone Up and Nike FuelBand, respectively. The Flex is available on Fitbit's website and major retailers. Be sure to check out our hands-on for more.
