“I've just had this for a couple of weeks (fast shipping from BACTrack.com, by the way), but I've been getting used to using it. At home, I've been able to learn what happens with one glass of wine, two glasses of wine, and three glasses of wine, and then what happens an hour or so after the last one, at bedtime, and the next morning (0.00). A few days later, I had a scotch out by the pool and tried the S80 Pro again. I'm noticing that I can tell, within reason, about where my BAC is by using the feedback from the S80 Pro. That's extremely useful. I wouldn't want to rely on that judgment, so I'll keep the S80 handy. I'm really happy that I could find a reasonably priced Pro version that is as accurate (I think) as anything law enforcement might use. I've never been tested by them, and I don't want to be, but I sure feel better knowing in advance what they'll see.”
“I bought it for 2 reasons, one make sure I don't over blow on my smart start and two don't ever be over again, if you use it a lot and get to know yourself with it, it shows that you don't have to fun hate just makes you more responsible”
“So much better than my old unit. Ready to use within ten or so seconds after switching on. Great little unit, extremely happy that I upgraded. Newer technology brilliant.”
“Currently have intoxalock installed and would get a red light fail afternoon following beer consumption which charges add too 100.00 dollars charge to reset. The backtrack allows me to be sure I'm at 0.00 alc before I attempt to start car”
