Buying advice

When choosing a personal breathalyzer, consider the sensor type: fuel cell sensors offer higher accuracy and reliability, while semiconductor sensors are cheaper but less precise. Look for FDA clearance or approval for quality assurance. Also think about features like Bluetooth connectivity for tracking, mouthpiece availability, and calibration requirements. For occasional use, a budget model may suffice; for frequent or serious use, invest in a higher-end device.
