What to know before buying

Health measurements are described as reference information and not intended for medical use. Battery life may vary with use. Some app functions and integrations depend on app version, device compatibility and region.
The listing's 256 MB storage and 256 MB RAM are separate stated fields, not evidence of additional or virtual memory.

Listing details to confirm

Listing details are inconsistent or unconfirmed: connectivity is listed as Wi-Fi as well as Bluetooth, while calling and phone compatibility are described separately. The water claims also vary between IP68 and 4.92 feet, but the usage disclaimer limits water resistance to dust and splashes and says not to swim, dive or expose it to water for long periods. Battery life is stated as 13 days, with 2.5 hours in a feature description versus 1.5 hours in specifications for charging. Confirm the selected listing details before relying on those figures.
