Hold your breath for 10 seconds then blow in to the breathalyser for 10 seconds if it say your 80mg per 100ml of blood your over the limit the mistake what most people do is they just blow in to the reader but what you got to do is hold your breath for 10 seconds that's why most people say they don't work people never read the instruction manuals.

No, waste of money and little more than a toy. Buy a decent quality one from Breathalyser Direct or UK Breathalyzer Shop - reliable and accurate.
