Become a better runner with the Band 3e Activity & Running Tracker from Huawei. The Band 3e features two modes of use: a wrist mode and a shoe mode, and it can automatically switch between the two. On your wrist, the Band 3e acts like many activity trackers, keeping track of steps taken, distance traveled, calories burned, sleep quality, and more. Switch to shoe mode, and the Band 3e will use seven data points to help you become a smarter runner. In either mode, the Band 3e can be used out in the elements thanks to water resistance up to 30m, and when paired with a Bluetooth-compatible smartphone, it can display incoming calls and message notifications on the 0.5" PMOLED display.
