I have used mine for several days and it still works. It is very good to tell you BAC after one drink, then two, and so on, waiting 20 minutes between each drink to find out your BAC. It is also good to determine your BAC after you have awakened. It is unfortunate that a 0.08 BAC is attained after only one 15 oz. beer and it's the BAC you might wake up at. A 12 oz. beer and your BAC should be around 0.06 if you weigh 250 pounds, which is below the legal limit and apparently 0.08 BAC is the limit at which you can tell you are beginning to be UI but you are still mostly sober. Two 12 oz. beers will put your BAC at 0.12. It is interesting to learn these things with this breathalyzer and it is quite the experience to learn these things with this tool. Discovering that very little alcohol makes ones BAC so high suddenly, but because of this device I now know how little I have to drink to be under the 0.08 BAC legal limit. 2 oz. of 80 proof liquor is a 0.16 BAC at 250 pounds. That's terrible. The only alternative is to not get behind the wheel of a motor vehicle after having any alcohol at all. Even a drop of alcohol will probably register on this breathalyzer, but I dont know that really, it may take a few drops. Read the directions on how to use it. ### ⭐ 1.0 out of 5 stars Doesn’t work at all *by S***E on Reviewed in the United States on July 2, 2022* I have had this for a couple months and unfortunately missed the return window. I have used this no less than 10 times and it has only worked once. It reads 0 BAC every time I use it regardless of how much alcohol I’ve had. Don’t waste your money ### ⭐⭐⭐ 3.0 out of 5 stars Accuracy? *by P***N on Reviewed in the United States on April 24, 2023* This thing is small and it's probably fairly accurate for a breathalyzer of it's size, but that's the problem. I have used this thing a few times but I could never figure out how accurate this is. It appeared to work three times out of five, though not consistently. It was fun while I had it. I think it'll work well as a gag gift. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/69503495-professional-breathalyzer-keychain-portable-breath-alcohol-tester-red-backlit-breath](https://www.desertcart.vu/products/69503495-professional-breathalyzer-keychain-portable-breath-alcohol-tester-red-backlit-breath) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-18*
