Engerwall Fitness Tracker
Score: 75/100
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 Engerwall S5-3 offers a 0.96-inch display, up to 14 days of battery life, IP68 water resistance, and a suite of health sensors across 16 sport modes. However, it lacks built-in GPS, has a modest resolution screen, and sleep tracking accuracy is questionable. Best suited for budget-conscious beginners who need basic activity and health monitoring.

Professional reviewers consider the Engerwall S5-3 a solid entry-level tracker, emphasizing its long battery, IP68 waterproof rating, and reliable step/heart-rate monitoring while noting the lack of built-in GPS, limited sleep accuracy, and modest display as trade-offs for its low price.
Everyday users generally like the lightweight feel, long battery life, and basic health metrics, but they repeatedly criticize the sleep and calorie tracking accuracy and occasional app sync problems.
Professional reviewers commend the Band 9 for its value-driven upgrades, especially the 1200-nit AMOLED display with ambient-light sensing, the 16 % heart-rate accuracy improvement, and the impressive 21-day battery life enabled by Bluetooth 5.4 and efficient sensors. They also highlight the stronger linear motor vibration and the lightweight aluminum frame, while noting the lack of built-in GPS and the smaller, lower-resolution screen as trade-offs against the higher-priced Pro variant.
Everyday users consistently praise the long battery life, feather-light comfort, bright outdoor-readable display, and reliable health tracking via the Mi Fitness app. Common themes include appreciation for the wide range of sport modes and water resistance, as well as the attractive color options. Recurring complaints focus on occasional app sync glitches, the absence of native GPS, and the modest screen resolution that feels low-end for notification detail.
