Incredible device. It gives fast readings in under 10 seconds and fits right in my pocket. The contactless feature is great when friends want to test their levels too.

Super accurate and very simple to use. The color-coded screen makes it foolproof. It gives me and my family total confidence before anyone gets behind the wheel.

Battery lasts forever and charging via USB in the car is super convenient. Far better than bulky old breathalyzers with replaceable tips. Highly recommended for every glovebox.
