I got this for my son. He has a couple drinks, came home and tested .45. We retested and it was wildly high. No Bueno ### ⭐⭐⭐⭐⭐ and felt like you really didn't feel comfortable with them driving home *by M***H on July 1, 2016* Have you ever wonder after you left a bar, maybe I've had one too many. Or had friends over, and felt like you really didn't feel comfortable with them driving home. Of course they fought you for the keys, all the while protesting, saying, while slurring, nah, I'm fine, as they stumbled out the front door to their car. Or maybe, you have a teenager that you have concerns over who they are dating. Sneaking back in late at night, with alcohol on their breath, but swearing, I haven't had a drop. Well, here's your answer. The Teswell Portable breathalyzer will take all the guess work out of whether or not someone has been drinking, or has had too much to drink. And it will keep up to 30 recordings, so no way of cheating the system with this. The monitor comes with a USB charging cable, 4 mouth pieces, and is easy as pie to use. The instruction manual takes only minutes to master. Setting the unit up for the first time is only a matter of pressing the ON/Off button in conjunction with pressing the Escape button. This sets up the BAC level. Also a timer. After that, just turn the unit on, blow into the mouth piece for 7 seconds and you get the BAC, Blood Alcohol Content of that individual. So, whether for yourself, your freinds, or members of your family, this is a great way to avoid embarrassment, heavy fines, jail, and perhaps even worse. DUI's are no laughing matter and drunk driving takes alot of lives every year on our highway's. Unfortunately many of those are young people. This is a step in the right direction. Great product, simple and easy to use. And one I couldn't recommend more highly.I was provided this product, discounted for the purpose of providing an honest review of the Teswell breathalyzer. It works exactly as described. I gargled with Scotch whiskey for the test. But if you so much as had gargled with Listerine, it would pick it up. Thanks for reading. Have a nice day. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/30816216-teswell-portable-professional-breathalyzer-lcd-display-breath-alcohol-tester-fuel](https://www.desertcart.vn/products/30816216-teswell-portable-professional-breathalyzer-lcd-display-breath-alcohol-tester-fuel) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-16*
