Xiaomi Smart Band 9 Midnight
Score: 80/100Rankings

The Xiaomi Smart Band 9 offers a bright 1.62-inch AMOLED screen, ultra-light design and long battery life for everyday fitness tracking. It sacrifices built-in GPS and a higher-resolution display, which may disappoint power users. Best suited for budget-conscious users who prioritize comfort and basic health metrics.

The ZURURU Y39 offers a lightweight 25 g design, 5-ATM waterproofing and continuous heart-rate and blood-pressure monitoring, making it a solid budget tracker. Its small 0.96-inch screen and lack of built-in GPS are notable compromises. Best suited for casual users who prioritize affordability, basic health metrics and water resistance over advanced navigation or large displays.
