Electronic Bad Breath Checker
Need to check if you are suffering from bad breath? Just blow into the sensor and the backlit LCD display will give you a breath quality reading on a scale of 1 to 6. Scoring a 6 means you better find a toothbrush, and fast. I particularly like the anime-esque faces that help you understand the severity of your breath reading.
 
The device is also able to measure your blood alcohol level, and will provide a reading in 0.5 increments so you know if you’ve enjoyed yourself too much to get behind the wheel of a car. You can find it at Japan Trend Shop for $59.
Available for $59 about £30

Nice gadget. Also there is written “Etiquette Checker”
How not to smell bad on the public…
Interesting it can check only breath? If I’ll check my fresh-made cake, will it give the result?
