Xiaomi Mi Band 4 review: A must-have budget fitness tracker under $50
Xiaomi continues to dominate the wearable space, with the Mi Band 4 offering several upgrades.
Every year for the last three years, Xiaomi has rolled out exciting new features to its Mi Band series. Last year’s Mi Band 3 retailed for just $25, offering a heart rate sensor, 5ATM water resistance, and a 0.78-inch OLED panel. The Chinese manufacturer dominates the wearable segment on the back of the Mi Band series, and it’s easy to see why — there isn’t another budget fitness band that gives you quite as many features.
