Performance:Works like a charm Quality:5 star as you can expect from Xiaomi/Redmi I love everything about this watch, especially with the accuracy of fitness tracking, sleep quality and heart rate measurement as well as admirable battery life. There's a built in GPS so you don't have to connect to your phone to map out your runs/hikes. There's even a small speaker for notification, calls and alarm creator19 · shopee.com.my
