“After drinking all night, it never registered higher than a .07. After my first beer - .07 after my fifth beer, same thing .07. I know for a fact I could not still be at a .07 afeter 3+ hours of drinking. I took repeated tests and would sometimes register .06. I just received this today, and already it is inaccurate.”
“Tried one at a friend's house a few days ago and thought it was cool. So, I ordered the C8. Straight out of the box, followed instructions to the letter, and it would only read 0.00% even after 3 glasses of wine. My wife tried also, same result.”
“Have had this product for roughly 1 month. Used this 3 times as instructed but thought the readings were off. Used it in the morning after an evening without alcohol and blew a .03. Having to send in for calibration after this short of a time will be frustrating.”
“I've bought two of the C6's for me and a friend and the C8 for me. I find it fun, and pretty dang accurate. The fun stops at the end of the night when you realize your judgement is off.”
“I will update when the 3rd c8 gets recalibrated. 2 traces 3 c8s bought to make a point. Not 1 of 4 them within .01 let alone +/- .005 like they say. Don't waste your money”
