The device gives you the result in about 5 seconds after blowing and the screen starts flicking red and blue when you are over the limit! Very nice feature.
Yesterday, I got out of a bar, I stopped drinking 2 hours earlier and thought I was sober, when I tested myself I still had 0.26 mg/l in me!
Great device, works very well, I like how quickly it sets up. I use it everytime i'm not sure if i'm sober and I can drive without worries.
