One thing that made the first generation Mi Band great was its simplicity. A minimalist pebble that fits into a silicone strap. Three indicator lights shine through the metallic surface to relay information. The rest of the interaction takes place on the phone in the Xiaomi Fit app.
The Mi Band 2 comes with a simple OLED scratch-resistant display where you can view information such as the time, number of steps, calories burned and heart rate.
