    This breathalyzer will help you stay legal. While this product will help you keep track of your alcohol consumption, I have noticed it is not as accurate as you would think it would be when the display shows a third decimal. I usually blow in it about 3 times and take the average. Also, there is a mode button below the start button that looks to do absolutely nothing. This is usually a sign of a product that was thrown into production "as-is" due to budget or product problems.

    Verified Purchase

    This is a must-have item if you like to go out and drink. Don't put anybody in danger by driving drunk and don't risk a DUI. No need to when for less than $$$ you can know your BAC and stay off the road. This thing works great!

  • Compact easy to use

    This is a great device. I love that it can easily be stored in my purse or glove box in the car. It is easy to use, easy to read and gives very accurate results. My friends all use it when we are out, too. I highly recommend this to anyone that likes to go out and have a few drinks. It could save you from getting pulled over.

    The product was received extremely fast. Haven't used it yet but bought it for general safety and precaution to prevent DUIs for myself and friends after a night out on the town. I would recommend that everyone has one on hand to check their sobriety level before getting behind the wheel.
