What to know before buying

Listing details to confirm

Battery life is listed as up to 24 days, but the supplied listing does not specify the operating conditions for that figure. Health readings are estimates, not medical measurements, and Pulse Ox is not available in all countries. The listing uses the word “Waterproof” and separately gives 100 meters in one field, while the product description says 10 ATM. Check the rating and usage guidance for the selected listing before water activities.
