Backlight Alcohol Tester is a portable breathalyzer for the Samsung Galaxy S4 / S3

For a little more than $20 ($20.45 to be exact) you can use the Backlight Alcohol Tester – Alcohol Analyzer from isweek.com to check your alcohol level. There are versions compatible with the Samsung Galaxy S4 / S3, Note and more.

The device features an LCD digital display that lights up in 3 different colors depending on the alcohol it detects on your breath. You won’t be required to install any special apps, just blow into the air hole and an alarm will buzz if the level is in excess.

They also claim that the Backlight Alcohol Tester has the ability to identify cigarettes, coke, coffee smells and prevent non alcohol gas to interfere the detected result. The fact that this gadget doesn’t require any software makes me think it’s only using the phone as a power source and nothing else. I’m not a drinker… anyone have experience with this type of gadget? Do they actually work?
