Fitbit Flex Slate

If you're looking for an electronic device that looks great and monitors your activities, the Fitbit Flex multisport tester is right for you. This striking pink waterproof bracelet is designed with a perfect universal fit. The innovative sensors can detect walking from jogging, and measure how long and well you sleep. This smart device counts the exact number of steps, calories burned and duration of each event.
The device is simple to operate by tapping the sensor and five different LED lights let you know its status. Fitbit Flex automatically synchronizes via Bluetooth with your Apple equipment and selected Android smartphones. Connection via Bluetooth allows constant access to your statistics, without having a significant impact on the battery life of your phone. A list of compatible devices can be found here.
