you know... to be completely honest.... the whole idea of buying a meter, testing yourself and expecting to know what your BAC is gonna be sounds like a terrible idea...

i think of it the same way i do radar detectors.. people think that because they have them, they will never get a ticket... well, i, for one know that it isnt true. i was clocked by aircraft on a highway going FAR over the limit because i was overconfident with my radar detector.
so, i actually blame that ticket directly on my radar detector... because i had a false sense of safety and security because i got so used to not having to worry about tickets.

i think the same could happen with a BAC tester. you could test yourself a few times after having 2 beers and think.. ok i know that im only at .06 after 2 beers... but what you dont think of is how much water you had.. maybe the days you tested it you had drank half a gallon of water, but one day you only drink one glass and have 2 beers at the bar.... BOOM.. dui....

make sense??
