It registers alcohol on the breath but I've never tested it next to one that reads bac accurately.

They kinda sorta work. You can pick up used roadside ones from LEA's online for under a hundred bucks but the calibration equipment to keep them in spec is not cheap.

For that cheap, I wouldn't be confident in its accuracy.

I've seen $100 meters that test other gases for safety along with drinky-drinky.

I figure if you've drank enough to be concerned, you're within the error rate of a cheap meter. IOW, I wouldn't trust it. I'd guess it's accurate enough to detect alcohol, but not how much.

A meter, even an expensive one, is not the tool for deciding this. Use your brain.

If you're inebriated enough that your brain is not working, don't drive. If you're unable to decide when said organ is not functioning correctly, stop drinking and/or never drive.

To me, it seems like a personal meter would serve one of two purposes:

Either you're one of those people who is completely wrecked around the legal limit, and you want the meter to replace sound judgement, or

You're the type of person that is very cognisant around the legal limit, but you realize that you drive like shit and might even get pulled over for suspected drunkeness while stone sober.
