    It’s fairly accurate! It always stays within a couple of number when you retest.

    This thing is amazing and it is pretty accurate. It's also great for parties. Everyone can test to see where their BAC level is at. This way they can determine if it is safe for them to drive, or to wait longer. I can't believe I didn't have one of these sooner in life.

    Without access to a professional breathalyzer I can't in good conscience give it 5 stars. Barring that, this product is great. If you find inconsistent numbers, odds are you're not using it correctly (and possibly drunk). Use it as a guide not an absolute. Compact and easy to use.

    It’s a fun little device to use. I got this on sale and thought I would use it on my wife after dinner when she drinks her glass of wine lol. It does work. I’ve used it on myself as well at home after taking a couple of shots. It connects each time good and so issues so far. It’s been worth the $ so far just to say NO you are not driving now!

    It is so important not to allow yourself or loved ones to drive under the influence of alcohol. Do not trust your drunk self to make that judgement. This device has consistently given us a standard similar to what law enforcement uses.

    Easy to use and helpful for people that don’t know how alcohol affects them. I have brought it to brunch with the ladies and had everyone guess before they test and it has helped open the conversation about being safe while drinking.

    I had a couple duis in my past. Don't drink and drive anymore. Had a class on calculating b.a.c. And I am great at math. This thing is dead on. Awesome. Not like a couple I bought years ago. I just want to know when im driving to work after hours of rest after drinking what my level is an d this thing gives me confidence.

    The unit does everything that it’s advertised to do. It’s good as a just in case if you plan on driving after drinking. Its only an assistant to you and your judgement. Use wisely.

    This device works as advertised but the audible signals are very hard to hear. That said, my hearing is far from perfect after years of flying military jets. I recommend this device if you need a small portable breathalyzer.
