Watch over your health with the Xiaomi Mi Band 3 Wearable Fitness Tracker. Following its successful predecessor, the latest wearable from Xiaomi comes with the same key features. The fitness tracker counts your steps, measures heart rate, and can even answer calls. The Mi Band 3 comes with a 0.78-inch OLED display, offering 128 x 80-pixel resolution. It uses Bluetooth to connect to your other devices and it has a 110 mAh battery, which is twice as much as the Mi Band 2. The fitness tracker provides 20 days of battery life so you don’t have to charge it at the end of each day. Furthermore, the interchangeable straps come in different colors, making it easy to change up your look. There’s also an NFC chip version of the Mi Band 3, which allows you to pay wirelessly.
