BACtrack Trace Professional Breathalyzer | DOT & NHTSA Compliant | Alcohol Tester with Police-Grade Accuracy | Portable Breathalyzers for Alcohol Testing | BAC Tester

I drive for a living and have found this upgraded product from the small square ones better made and more reliable in measurements. Can’t say how much I always have in my blood but no false positives (0.00) and reasonable if not perfect readings when coming home from dinner or heading to the corner store. Absolutely love the confidence of knowing when is too much (even if you can’t use these - or any consumer product like them - in court). PSA on the last bit :)

I've been an Officer for 30 years, and I was extremely amazed how well this tester worked and the accuracy with it. I will be curious how long it lasts, but for now, I would recommend it to anyone. The key to alcohol testing is to wait 20 minutes before the last drink. No gum or anything else in the mouth, period! It will throw the test off. It's the same procedure in the Police Dept.

This works great. Just the thing for after the party. Drink but don't drive. Use the breathalyzer to be sure.

Works well and is super easy to use…

Buena calidad y precisión moderada

Unreliable. This device does not work after 1 month of use. Does not meet expectations.

Excellent product, very accurate.

I wanted to see about testing my BAC if I ever needed to do so. This device seems to be accurate. I tested myself during different drinking episodes. My wife, who didn't drink, would always register a 0.000. While I was drinking, I would register appropriate increases with each drink. It is true that if you drink alcohol, you must wait at least 10-20 minutes to get an accurate BAC reading, but I'm guessing it doesn't always mean that what you last drank has been absorbed and circulated in your blood stream. Anyhow, the readings increased with each drink. The opposite, but appropriate readings were scored through the night. With every few hours, my alcohol levels were decreasing and my 7 am reading was all zeros. Anyhow, the readings seemed appropriate, and they also correlated with what type of buzz or disorientation I was feeling at the time. To note..... the device will wait almost a minute to provide another reading, when the last reading was really high... like BAC of 0.46 (which was registered right after taking a whiskey shot). So it waited about 50 seconds to let you take another reading. Seems appropriate though, because such a high reading might require a bit of time to let the device dry out and maybe reset? Anyhow, I like it. It seems accurate and useful.
