This gadget could save your life or the life of someone you love.  Connect the Samsung Alcohol Tester to your Samsung Galaxy S4, Galaxy S3, Note 2 or Note 3, blow into the air hole and exhale for 3 to 5 seconds for an alcohol breath test. Watch the LED screen register Green for Normal, Yellow for Caution or Red for Danger which will then trigger the voice alarm function. Small enough to slip into a purse or pocket when you head out for a night on the town. Also available for iPhone 5/5S/5C, iPad4 or iPad Mini.
