2024 Upgrade Breathalyzer

nice compact digital meter. Intuitive and easy to use. It gave me a sense of real accuracy. I have had other units in the past but I did not trust the readings. This deice seems to be made well and work properly - which is all I can ask.

As the other reviews have said, follow the directions. I purposely tried to create false reading when I first got this to see if it would be accurate. If you wait after having a drink of anything, eating, etc and keep the tubes clean and recalibrate the device after a while not using; in my experience it has performed as exactly as advertised.

don't waste your money, at first I thought this device would be very useful and make me feel safer when I do drive. Initially it seemed to work fairly well and gave readings that I felt were reasonably accurate, but after about a week of testing it got to where it would only work once per day, if that. When it works it will give you a beeping sound when you have blown into it long enough and then give you a BAC %, now I am lucky if I get the beep and a BAC even one time in a day. Stay away from this product, nice try but poor quality

This is great, I have a interlock in my car and always need to ensure I have nothing in my system the next day after drinking to go to work. The accuracy is a little wonky and it glitches out during the blow cycle sometimes but I use it very often and it has never said I was a 0.00 and it not be accurate. It is sensitive to certain foods and when you brush your teeth so make sure to give it a few minutes before using after eating or brushing.

Overall it gives me piece of mind and it accurate when alcohol is present. I think the preciseness of the numbers could improve, but overall a good value for the money. Sometimes it beeps and I don't know why and does take a bit to reset and countdown until it is ready for you to blow (20 seconds, sometimes twice that you have to wait)

Small device but works as expected, comes with a cute little carrying case that is subtle and inconspicuous. color makes it easy to read. Great to keep in the car if you’re at a party and want to be safe driving home.

Compact (as seen in comparison to sunglass case), long battery life, and appears to be pretty accurate. Great for the car or if you have friends over who you think may have partied a little too hard.

Works great, seems to be accurate, and very easy to use! All of this at a great price!!

Tried it out last night, blew 0.19 had 3 shots and a drink (yes i drink excessively) waited a half hour or longer and tried again was still .019, tried it the next afternoon 12+ hours without a drink and it showed a .10 repeated the test over and over every 30 seconds and each time it fell substantially 3 minutes after a .10 it was showing .06

Tried it after 9 drinks still says 0% low , doesnt work
