This is junk if you’re serious about it. I have the S80 Pro which has a fuel cell in it, I believe it is a police grade (whatever that is) breathalyzer. You have to send it in every 100 or so uses to get it re-calibrated.
It is nice to have, I used it briefly to help learn better where I was. I used to be nervous on the road after 4 beers in 2 hrs despite feeling perfectly fine. Turns out it was because I was fine. I always thought it was easy to get to .08 and screw up, while it is…it isn’t that hard to avoid it!
Also makes a good thing to pass around at parties but the problem is it picks up alcohol on your breath if you’ve just drank. I can take a sip of my drink, blow .25 when it was my first drink of the night.
I have a friend who is a cop. He told me one of the main reasons for field sobriety tests is to make sure they take enough time prior to issuing the breathalyzer so you have an accurate reading.
That being said. I had a similar but different model. It was fun while it lasted, but you have realize its utility. I wouldn’t use it, blow a 0.07 and think “great, gimme the keys I’m perfect!” because the margin of error on these glorified toys is pretty high. But it was a good conversation piece.
Without digressing to our Poli"ticks" thread here in the main offer,
there is a huge difference in slamming down a few at the local inn, and having a meal with a glass or two of wine.
This is yet another tool, and used prudently, could help avoid a DUI; which I’ve never gotten.
