Alcohol tester pen - not for halitosis testing - Engadget Simplified Chinese

We all know that drinking and driving are always on the opposite sides of morality and law, but sometimes it's really hard to tell if you've had too much before driving (maybe by then you're already drunk); so, the appearance of personal alcohol verifiers is significant. Of course, the British retailer Boys Stuff knows that many people are interested in such products, but they would still rather spend more money on getting drunk. Why? Because earlier products were generally too expensive.
