The first things we notice on the Flex are the waterproof contacts. This is good news for those who might be sweating while wearing, or tearing down, the Flex.
For the record, the Flex claims to be water-tight up to 10 meters, or 264 simultaneous Gatorade showers.
This tiny gizmo fits snugly in its USB charger when its lithium-polymer battery needs juice.
Not to worry, it won't take the place of your smartphone on the charger each night—this little gadget has a reported battery life of 5 days.
