Breathalyzer, Professional-Grade Accuracy Alcohol Tester with USB Rechargeable, Portable Breathalyzer with LCD Digital Display and 10 Mouthpieces

This product works very well. It also gives an accurate reading and is simple to use.

Excellent breathalyzer with comprehensive accessories! The device comes in a sturdy protective case and includes everything you need: multiple mouthpieces for hygienic use, a USB charging cable, and clear instructions. The bright green LCD display is easy to read in any lighting condition. The compact design makes it perfectly portable, and the simple two-button interface is straightforward to use. Great value considering all the included accessories and professional build quality. Highly recommended for anyone needing a reliable personal breathalyzer.

Very useful device for when you need to know your BAC. Less expensive than others on the market but so far it has been very accurate in my testing. I appreciate the carrying case and USB charging too.

This breathalyzer is completely unreliable. If you're at zero it will blow zero. But if you're at any other number it's almost double than what it actually is. If your at 0.05 it's likely to say .12 or even higher. If you have an IID do not rely on this device.

It works like it says it should! I have had another one that worked sometimes and then it just died after a few months and I couldn't get a rechargeable battery for it. This one is a lot nicer has a cool case with it which the other one didn't and that makes it nice to carry around if you need to check your friends make sure they sent me driving while drinking! That means a lot when you show them what their alcohol level is! It could definitely save a life.

I've experimented with this device and have found it to be accurate, informative, and easy to use. The price was on point and its quality seems to make it a good value for your dollar. Having one of these around is wise if you ever drink alcohol.

Good seller, purchase was shipped on time, quality good, would buy again.

I love whipping this out when I host parties, as it get some laughs and interest. Super easy to use. Comes with additional mouthpieces inside the case, so it's clean and easy to store.
