Mi Band, a fitness tracking wrist band that monitors your fitness and tracks your movement ( walking or running ) plus your sleeping pattern and use it as a smart vibrating alarm to wake up feeling better. Featuring the industry’s most power-efficient bluetooth chip and accelerometer, a single charge on this waterproof device will last up to 30 days.
Better yet, the band (http://www.tinydeal.com/fashion-new-xiaomi-miband-smart-bracelet-silicone-band-watch-p-139192.html ) doubles as a security token that automatically unlocks your phone. The technical gubbins all live inside a small alloy body with LED notification lights. This alloy device can be slipped in and out of different colour rubber wrist straps to suit your style, and there were even some more smart concepts shown too including a leather option.
