The smartband does not have a display therefore there is no option even to check time. The device hosts a microUSB port for charging. Sony s fitness tracking bracelet is IP58 certified which means the device is water resistant and dust proof. Although the device is available in Black, the user can change the colour of the bands. The bands available in Green, Purple and Orange has to be bought separately. Very much like the other fitness trackers, the Smartband tracks movement via an accelerometer. The primary function of the lone button is to switch from day to night mode but it can also be used with a handful of compatible smartphone applications. The battery life on the device is satisfactory and fits at the price segment.
