Breathalyzer, High-Accuracy Portable Breathalyzer with LCD Display, Upgraded Personal Alcohol Tester for Home Use, Includes 10 Mouthpieces

It has been a few days since I last used it, until today when I drank alcohol and tried to use it for testing, the result was 0.02, it doesn't work at all. It insults me. Trash...

reasonable accuracy, tested 0.006 when i'm not drinking. comes with plenty tips for different people to use. the machine also comes with a little storage space for a tip to be carried around. one slight disappointment is the lack of batteries, makes it not ready to use if you don't have 3 AAA batteries lying around.

It says .021 for me and someone else who didn't even drink. The directions say it will say 0 if you blow, and with out even blowing it also read .021.

Breathalyzer, High-Accuracy Portable Breathalyzer with LCD Display This lightweight breathalyzer possess one button, and needs 3 AAA batteries. It' comes with a plethora of mouthpieces, and not a lot of instructions. While I was completely sober, I confirmed a solid 0.0. But, I handed it off to my partner after a few drinks, and it took him several tries to get the little machine running. I guess it's a little temperamental. I gave him 2 different readings, but they were about what he expected given the amount of drinks he had, and both readings were relatively close to the other, within .004 of each other. It's certainly okay for some college kid to have for parties, but that's about it.

Gives false reading
