I was so hoping that this would work. I had read a number of reviews on the various home-BAC devices and this one seemed to have the fewest negative reviews. Unfortunately, it simply never worked - ever. I did a little home test of the device. Blew prior to having anything to drink. .00. Drank a two-shot drink, waited 20 minutes, blew. .00. Not a chance I was .00. Also, some of the function buttons didn't work. Returned it. Maybe I just had a defective one, but I won't be taking the chance and getting another.
What's not so great: Never registered anything above .00.
