TBAC√ is the test you can trust - meets both rigorous scientific standards and the requirements of the FDA for accuracy, ease of use, reliability. Just saturate the test strip with alcohol and read your result: it shows when you're sober (0.00), when you've had a little bit to drink (0.02 to 0.04), if you've had too much to legally drive (0.08), or if you are really very drunk (.0.30 - 5 times the legal limit!).

Good value, works well.
Does what you need. Shows nothing if not drinking, and shows dark blue if pretty well intoxicated. Will buy more as needed.
