Junk
Complete junk. Do not trust this device. I've personally owned several breathalyzers the best I've found is the alcohawk that I purchased from the local CVS for about $60. This device told me I was at .08 after 5 shots of fireball, 4 jagerbombs, and 5 beers in 3 hours. The math on a 215lb man should put me at about .13...ish. yes I have a tolerance obviously but that's not the point. I then tested it by taking a shot ashed immediately using the device the alcolhawk would be blown up (.45ish) this one was at .12... no way.
