There is such a problem: Can I drive after drinking? So I bought this alcohol tester after I carefully selected it. The device works very reliably and the measured values are very accurate. Since there is only one button, switching units is also very fast and very simple. The size is just right, it is suitable for hand control. I will keep it in the car and stop me before drunk driving. Compared with the fine and the cancellation of the driver's license, the money is definitely worth it. Review: Very cheap. A gag gift but not useable - Very cheap. Readings are always extreamly high. Even let my 10yr old blow into it and it read 1.9 DANGER Dont by this unless for a gag gift. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 3.7 out of 5 stars 12 Reviews | ## Images ![WEIO Breathalyzer, Professional Alcohol Detector Breathalyzers Tester Portable Brethalyzer Highly-Accurate Result Fast Respond Speed Alcohol Breathalyzer with LED Screen and 5PC Mouthpieces (Blue) - Image 1](https://m.media-amazon.com/images/I/51fyOXKBVJL.jpg) ![WEIO Breathalyzer, Professional Alcohol Detector Breathalyzers Tester Portable Brethalyzer Highly-Accurate Result Fast Respond Speed Alcohol Breathalyzer with LED Screen and 5PC Mouthpieces (Blue) - Image 2](https://m.media-amazon.com/images/I/6188lVu7MwL.jpg) ![WEIO Breathalyzer, Professional Alcohol Detector Breathalyzers Tester Portable Brethalyzer Highly-Accurate Result Fast Respond Speed Alcohol Breathalyzer with LED Screen and 5PC Mouthpieces (Blue) - Image 3](https://m.media-amazon.com/images/I/61VmqWE5A6L.jpg) ![WEIO Breathalyzer, Professional Alcohol Detector Breathalyzers Tester Portable Brethalyzer Highly-Accurate Result Fast Respond Speed Alcohol Breathalyzer with LED Screen and 5PC Mouthpieces (Blue) - Image 4](https://m.media-amazon.com/images/I/613z4r-CJ2L.jpg) ![WEIO Breathalyzer, Professional Alcohol Detector Breathalyzers Tester Portable Brethalyzer Highly-Accurate Result Fast Respond Speed Alcohol Breathalyzer with LED Screen and 5PC Mouthpieces (Blue) - Image 5](https://m.media-amazon.com/images/I/61XgvGZGK9L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's a great breathalyzer *by Y***A on September 21, 2018* I like to go out drinking with friends.

Readings are always extreamly high. Even let my 10yr old blow into it and it read 1.9 DANGER Dont by this unless for a gag gift. ### ⭐⭐⭐⭐⭐ Portable Breathalyzer! *by Y***A on October 2, 2018* This alcohol tester is easy to use, we just need to pass one of the nozzles through any of the holes on either side. Then we press the power button at the bottom of the screen. We will observe that the countdown starts (warm-up is 15 seconds) and we have 10 seconds when it is finished. After inhaling, you need to blow with force for 3-5 seconds. We will immediately see the test results on the LED screen, which has a blue background and can be used perfectly in the dark. After the test is over, the screen will automatically turn off after 10s The results are very accurate! --- ## 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.us/products/80535925-weio-breathalyzer-professional-alcohol-detector-breathalyzers-tester-portable-brethalyzer-highly](https://www.desertcart.us/products/80535925-weio-breathalyzer-professional-alcohol-detector-breathalyzers-tester-portable-brethalyzer-highly) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-07*
