“First, Youtube Detroit Police Bactrack. That piece is convincing to me, but just to be sure, I compared side-by-side three (3) BACtrack C6's with four (4) friends over a few nights of carefully monitored drinking--with and without food intake. Bottom line: All tracked nearly the same. I am. a. fan.

“The size of the keychain BAC is very nice. Take it with me whenever I go out on the town. Using the app is fun and a great conservation piece not to mention the information it provides for a safe night out.
Cheers!”
“I keep one in the truck to check before leaving a restaurant or bar, and another one at home to check guests before they leave. Great accuracy if the instructions are followed.”
“This is the 6th breathalyzer I have purchased from BACtrack and all have worked very well. Some are over 8 years old, with only one recalibration so far, on the oldest, a Pro 80.”
