  • Multi-Functional Measurement Display

    Simultaneously measures blood oxygen saturation (SpO2), perfusion index (PI), and heart rate, displaying dynamic graphs in real-time on a high-definition OLED screen for intuitive and comprehensive information presentation.

  • Simple and Easy to Use

    One-button power on/off, delivers results within 8 seconds, comes with battery and lanyard, significantly lowering the barrier to entry and making it suitable for all user groups.

  • Intelligent Low-Energy Design

    Automatically powers off after 8 seconds of inactivity, effectively conserving battery and extending standby time, enhancing convenience for daily use.

Product Cons

  • Non-Medical Use Limitation

    Explicitly stated for sports and aviation use only, not a medical-grade device, severely limiting its application and credibility in real medical/health monitoring scenarios.

  • Questionable Accuracy and Display Readability

    User feedback indicates unstable readings and errors, and insufficient screen brightness makes it difficult to see in strong light, impacting the core measurement experience.

  • Actual Battery Life Does Not Match Claims

    Despite low-energy marketing, multiple users report fast battery drain, with actual lifespan far below expectations, affecting long-term cost of use.

  • Lacks Advanced Data Features

    Lacks smart features like app connectivity, data history logging, or custom alerts, unable to meet users' more comprehensive health data management needs. (Inferred based on experience with similar products)

  • Unstable Quality Control and Durability

    Some user feedback indicates unreliable product quality, with potential batch or individual manufacturing defects, impacting overall product trustworthiness.
