“Take a reading, shows low BAC (like .01). Take one small drink of beer, then immediately retest, and the reading spikes (to like .16). This thing doesn't work, and I certainly wouldn't trust it. I wish I could get a refund!”
“As cool of a concept as it is... it's terribly inaccurate. I tried it once, it seemed right, but after two drinks, it said i should probably be dead. after a bottle and a half of champagne, it said I had a BAC of .014... so i can still drive? I would not recommend if you are looking for accurate results...”
