Bactrack Keychain C6 breathalyzer Complaints

Johnny Lightining – “Had a few drinks and compared the results to a different breathalyzer. It read less than half. I kept drinking. The results were completely repeatable. But always half of the other unit I have. I got pretty drunk. The unit still displayed 0.07 while other unit showed 0.018. The results were repeatable but result was useless.”

MP85 – “Have this device for couple of months. I find the results are quite inconsistent. A couple of beers I will blow its 0.000 and then blow again, it shows 0.02-0.03ish. The false zeros scare me.”
