I bought the device for driving school as a demonstration model and because of the new legislation in France. Today I had the opportunity to compare the measurement results directly to a mobile police unit, thanks to a friend in the police force. Result at the police unit: 0.2 per thousand, on the breathalyser ACE EASY AL5500 showed the measurement result 0.23 per thousand. In the measurements, the 30-minute limit has been complied with since the last alcohol consumption. Result: The EASY AL5500 Breathalyzer ACE gives sufficiently accurate and reproducible results. The device is small and portable, so you can carry it easily in the vehicle. Therefore I a strong buy recommendation.
It is striking that the breathalyser ACE EASY AL5500 long time needs until it is ready for operation, but if it is at operating temperature, it goes fast. Worth mentioning is also that the device by the manufacturer is recalibratable and is adhered to the package a Kalibriervermerk date.
