What to know before buying

The listing identifies this as a recreational-use device, not for medical use. It advises remaining still during checks, and customer feedback describes some readings as taking 20 seconds or longer. The stated 70% - 99% SpO2 range and +/-2% accuracy are listing claims, not independently verified performance.

Customer feedback praises data management and the ability to track readings and reports over time. Reports about reliability, accuracy, battery life, Bluetooth connection and value are mixed, and some customers describe readings as slow, taking 20 seconds or more. For buyers interested in the PO3's app-based trends, those concerns matter because useful tracking depends on obtaining readings and syncing them reliably. The overall rating distribution leans positive, but it does not establish consistent performance for every user.
