Customer Ratings & Reviews

I currently have an interlock restricted license, so I bought this breathalyzer to make sure that I have no alcohol whatsoever remaining in my system before attempting to start my car. While it has worked for my purposes so far (accurately informing me when my BAC is .00 and I'm safe to drive) - the actual BAC it displays is nowhere near correct. It's consistently shown me a BAC of .10 or above after only one beer, which is impossible. So - while I'm perfectly happy with it for the purpose I purchased it for - I wouldn't recommend it to someone who's looking to obtain accurate BAC readings.

Travel size and ready to go! It's accurate easy to take everywhere and can make your drunk friends sit down for a minute before they slip the key into the ignition and get themselves a DUI.

I have used it at a few parties and shows a good idea of the BAC levels of people but too much use at a time seems to scew the results.

Works wonderfully. Had a New Years Eve party and pulled it out. Some had to spend the night. Truly a eye opener. Bought my spouse and Son one. It showed them a thing or two.

It seems to be in a good condition. I gotta test later when I actually drink alcohol.

Purchased earlier in year for personal use. Friends and family thought it was brilliant to own this to gauge ones' alcohol use. Many asked where they could buy one for themselves. So for Christmas I bought this as a gift for almost everyone on my gift list (ages 22 to 60). They all loved it! The younger ones especially loved it--for many it was their best gift and they immediately began facebooking friends on what they got for xmas!

Great product that is easy to use and very afforable/good value.

Like the small size. Is easy to carry around and keep handy when needed. Seems to do an excellent job of measuring and makes you realize when you have had enough to drink.

We used it to check "any at all" type consumption. Recently smoking menthol cigarettes seems to add about .03....other than that, did exactly what we wanted...

THIS IS A GREAT PRODUCT, WE HAVE TESTED IT AND IT SEEMS TO BE PRETTY ACCURATE, A DEFINITE BUY

I bought this for fun, i would not rely on it to avoid a DUI.

Got my keychain backtrack in the mail today, and decided to give it a test run. Twenty-four hours after my last drink, I did a dry run on the breathalyzer. Not surprisingly, my reading was .00. Accoring to directions, you must wait 30 minutes after your last drink for an accurate result - and I complied. One 12 oz. beer and thirty minutes later, my BAC reading was .06. Wildly innacurate! According to most research, one 12 oz. beer (depending on height/weight/gender results may be +/- .01) results in a BAC of .02.

this thing read 0.08 after one drink! Then after 5 uses, it would start to give 0.00 every other test.
