“For the first month it appeared to work very well. I may have used it once per weekend and it seemed to be accurate, though I did not have any other device to compare it with. Then it stopped reading anything over .02%. I've used it during roughly 5 different settings where I was well over .02%, as well as others that tested it, and it read either .01% or .02%. Unfortunately, this moderately nicer model doesn't appear to be any better than the cheap ones.”
“tried it after a few beers and a shot of bourbon in a 1 1/2 hour period and it read .04%
i could not tell if it was higher as this is the top limit that it reads”
“Since buying my BACtrack I've experimented at home to see how my BAC rises and falls based on the number of drinks, time elapsed, and having a full or empty stomach. I have found that I need to wait a quarter hour after drinking to avoid an overly high BAC or at least to rinse my mouth out before taking the test. It seems residual alcohol in the mouth immediately after taking a drink gives an unrealistically high BAC. But the breathalyzer provides good basic information for making decisions when I'm out and about.”
“I purchased the BAC Track to be more aware of my BAC after consuming alcohol and considering driving. While I like how simple the product is, how small it is, I question it's accuracy at both the high end and the low end. After consuming two glasses of wine and waiting one hour, I registered a .09 (was expecting a .04 max). One night I had a glass of wine, waited one hour and registered a .02. I had a piece of bread immediately after registering the .02 and for 60 minutes registered a .09 (with no additional alcohol). While I appreciate this device, I do not believe it's accuracy is there unless you are at a .00.”
