GREENWON Alcohol Breathalyzer, Professional- Grade Accuracy Alcohol Breath Tester, Portable Blood Alcohol Tester Digital Blue LCD Display with 20 Mouthpieces for Personal & Home Party Use

I've been using this at-home breathalyzer for a while now, and it's been a game-changer in ensuring I make responsible decisions after social drinking. Its compact design, ease of use, and rapid, accurate readings stand out, giving me confidence in its reliability. The device also features a backlit display for easy reading in any light condition and comes with extra mouthpieces, making it hygienic for multiple users. A must-have for anyone who values safety and responsible drinking habits.

If you have a breathalyzer in front of you you blow a long blow, you can do that with this, but if you were to blow hard and fast your bac levels go up but if you hum into it is a less number.Not consistent*experiment completed 4/1/24 Dyngus day Cleveland ohio. *Product failed

🔵 The Not So Great:When your BAC is in the danger zone, it emits an extremely loud and annoying alarm that, as far as I can tell, cannot be acknowledged or muted. This can be quite inappropriate in many social settings. Additionally, my unit did not come with the indicated 20 mouthpieces but only had 5 on board, accessible from a compartment on the back of the device. However, given the need for regular cleaning, having 5 mouthpieces should be sufficient for most users.🔵 Overall:Having a basic understanding of how BAC testing works and the natural fluctuations in BAC levels from breath to breath, I expected a degree of variability in the results. Despite my familiarity with such devices, I encountered challenges in obtaining consistent and accurate readings, even after carefully following the instructions. It's important to note that this breathalyzer is more of a novelty item than a scientifically precise measuring device. However, considering its affordable price, it may be suitable for individuals who are not seeking highly precise BAC measurements and are content with a rough estimate.

5 stars

It seems to work well. Appears to be accurate. The downside is that it's tones are LOUD. Will draw attention when it's used, especially if you test above .05
