It doesn't work! Feel bad for anyone who actually intends to use this to see if they can safely get behind the wheel.

Even though this breathalyzer says it has a range from 0.00% to 0.19% BAC it will only read the max every time I blow in it. Even if I've only had one sip of beer it reads the max. I read the instructions and it says to wait 15 to 20 minutes and don't eat or smoke before testing, even following those instructions the alarm goes off and tells me I've had too much to drink. I should've seen the rating before purchasing.
