After only 3 glasses of red wine over 3 hours at a restaurant I got pulled over and blew a .09. Women process slower, blood alcohol climbs as you sit and bottom line you can feel fine and you aren't. After that experience I now either don't drink or test when I do. This is my second unit and it is great. Just keep in my purse and it saves my butt and my friends butt. Just knowing when to sit a bit longer to get in to the safe zone is WORTH IT. Easy to use, seemingly accurate, and has the ability to save a first time offender $10,000 and a second time $20,000! BAC is the real deal.
I purposely used it after 1 beer, then 2, and then 3. I carefully obtained the readings so I know my baseline drinking measures. This device offers the feeling of security BEFORE you get into your car and If you should call for a ride. I make sure I'm 2one hundredths differential before I leave.
I have the S80 Pro model. I have compared it to the one I use in a professional capacity and it holds its own. This thing is accurate. Mind you, the one I use in a professional capacity holds up in court so I would say that this one's accuracy is rather dependable. You should get it calibrated yearly as recommended to maintain its accuracy. The process is quick and easy and these guys stand by the quality of their products.
