Bactrack Trace Breathalyzer | Professional-Grade Accuracy Dot & Nhtsa Compliant Portable Breath Alcohol Tester For Personal Professional Use

Bought this because I had always heard the "the legal limit is 0.08" line, but that really means nothing if you've never had your BAC tested ever in your life. At first, the results were all over the place and I even had one that read insanely high for no reason. But then I realized I had still been drinking my drink 2 minutes previous and the instructions say to wait 20 minutes after eating and drinking before testing. After that I finished my drinks and waited at least 20+ minutes before testing and did 3 tests in a row - they read 0.04, 0.039, and 0.039. Probably 25 minutes after that I did another test and got 0.038. These results seemed very consistent, so just make sure you actually follow the "no food or drinks for 20 minutes" rule if you want accurate readings. I'm guessing a lot of the more negative reviews on this thing are from people who were not following the directions, because at first I was like "what the ... why is each reading so different" until I started using it correctly.

Me gusta que es 100% efectivo, aunque hay que agarrarle el modo; soplar en el momento indicado y esperar a que suenen dos pequeños clicks. Lo recomiendo.

This arrived well packaged in a branded cardboard box. It is compact and well designed. Set up is simple and easy. Just follow the instructions and leave at least 20 minutes before testing. I found that the results were very consistent. Handy little gadget. High price point but that is reflected in the quality, design and accuracy of the product.

Works well. Like the LED readout showing how much power is left. Takes both USB sizes

Completo ed intuitivo, ottima ripetibilità delle misurazioni fatte a parità di condizioni dei test effettuati!
