Chinese vendor Xiaomi will launch its new rock-bottom-priced fitness band on Monday. Known as the Mi Band, the device will sell for 79 yuan, which translates to about $13 or 10 euros. The first wearable gadget from a company known for its increasingly popular smartphones, the Mi Band can monitor and help with your exercise routine, wake you up when you oversleep, and last for 30 days on a single battery charge. The Mi Band can also track your swimming routine since it’s water resistant at a depth of more than three feet. So what’s the catch? Well, for now the device apparently will be sold only in China, and Xiaomi has yet to reveal any global availability. Like other fitness bands, the Mi Band takes on extra powers when paired with a smartphone such as unlocking your phone when the two devices are nearby — but this bonus works only with Xiaomi smartphones.
