The Digital Alcohol Breath Tester is a great gadget that will let you know if you're too piddled to be left in charge of a moving vehicle. This pocket-sized breathalyser is incredibly easy to use, even if you have drunk yourself insensiwobble (which is two drinks more than insensible) - just blow over the sensor for 3-5 seconds while the built-in timer counts down, then read your test results from the nifty built in LCD. If it reads between 0.05 or 0.08 BAC* the alcohol tester will beep and display a caution symbol to show that you are dangerously close to or over the limit**. If you test between 0.08 and 0.19% the LCD will display a warning symbol letting you know that driving is most definitely off the cards for the evening and probably most of the following day too. Pop this in your pocket before your next night out and keep an eye on your drinking with this hi-tech portable breathalyser.
