Was a gift, opened but never used it

PROTECT THE CORE KETONE-METER INTENT: This breath ketone meter retains the current main-selling logic: a 32-bit integrated chip processes the breath-acetone signal and presents a direct device result. It supports personal keto-routine comparisons without describing breath output as an equivalent blood/urine ketone value or a medically validated fat-burning calculation.

FIVE-SECOND SAMPLE WITH A REPEATABLE TECHNIQUE: Power on and wait for the device prompt. Take a full breath, then exhale steadily through an open mouth towards the sampling openings for approximately three to five seconds from around 1 cm away. Using a similar distance and exhale pattern helps reduce technique-related variation between personal checks.

MORNING ROUTINE FOR EASIER COMPARISON: Current seller guidance recommends a check after waking and before eating when practical. Keeping time of day and surrounding conditions similar can make personal patterns easier to review. Food, drinks, fasting duration, activity and breath technique may all change the displayed result.

RECHARGE THROUGH TYPE-C: The built-in battery supports repeated use without replacing disposable batteries. Charge for at least 30 minutes before first use according to the current seller instructions, then recharge when needed. The stated maximum of up to 30 days depends on warm-up cycles, number of checks and charging habits.

ONE-BUTTON CONTROL, CLEAR PRODUCT LIMITS: The straightforward control suits both new and regular keto users at home or away. The meter is a personal breath-acetone reference tool. It does not directly measure circulating ketones, prove that a user is in ketosis, verify a fitness result or provide a diagnosis or treatment decision.
