What owners single out
Review 1 flags inaccurate SpO2 sensors, matching video reviewers' concern about health sensor reliability.
In their words
“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”

“Great battery and awesome screen. The aluminium frame is appreciated and gives the watch a more premium look and feel. However, the sensors, particularly SPO2 are very inaccurate. SPO2 constantly records dangerously low blood oxygen levels (89-92 usually) which is completely inaccurate compared to the pulse oximeter I have which has me around 95-98. The steps and heart rate are also over calculate”
