Many people enjoy the occasional drink, and it is no harm in that, but unfortunately some actually decide that they are capable to drive, even if they had been partying all night.
With the Breathalyzer Alcohol Tester – Deluxe Edition, you won’t get to the point where you have to lose your license just because you had a couple of drinks. Just turn it on, blow into it for at least 5 seconds and the little device will indicate if you are sober enough to drive.
I think that 10.28 € is not a high price to pay, when your life is involved.
Drive safely! Â Â
