Purchased December 2025. Used a few times. Comes with box (& bag). USB charging cable is unused and unopened. Amazon Title (copied and pasted): "Ketone Breath Analyzer, Ketone Meter, Breath-Based, Low-Carb Diet, USB Rechargeable, Non-Contact, High-Precision, Ketone Meter, Displays Ketone Concentration in Breath, Portable, with Japanese Instruction Manual" Amazon Product Description (copied and pasted): About this product: 【Innovative Ketone Breath Analyzer】This product can easily measure the acetone concentration in a person's breath. The measurement results are divided into 0-6 levels. The ketone breath measurement method is a more accurate and convenient method than urine ketone testing. 【Non-Contact Ketone Meter】Breathe into it for 5 seconds and quickly detect the ketone concentration in your breath. Since it doesn't use a mouthpiece, it's very hygienic. You can lightly breathe into it from a distance of 1 cm, making it a hygienic home ketone breath analyzer that can be used by more than one person. After turning on the power and allowing for the warm-up time, you can easily measure the ketone concentration in your breath by simply breathing into it. 【Measurement Method】Extend the sensor part. Press and hold the power button for 3 seconds to turn on the power, and the product will enter a 99-second countdown for preheating. When the preheating is complete, the main unit will vibrate, and the blue indicator light will flash, entering the measurement state. In the measurement state, bring your lips close to the breath inlet, maintain a distance of 1 cm, and breathe into it for 5 seconds. To measure correctly, preheat for 99 seconds before measuring, so please wait a moment. 【Tips for Use】The best time for continuous monitoring is within 30 minutes of waking up in the morning. Feel free to self-measure at other times. Please do not use it as a reference. Do not measure ketones immediately after exercise, as ketone levels are lower after exercise. It is recommended not to eat for 1 hour before measuring, as the consumption of certain foods, such as coconut oil, may affect ketone values. Thank you for viewing.
