There are few things more embarrassing than being caught out with the wrong flavor of breath. Bad breath comes in various forms, ranging from the chronic garlic yawn to the rambunctious alcohol whiff, which can often kill a pot plant at 20 meters. So how to make sure you’re not one of the perpetrators of such infamy on those poor souls around your person?

Well you could pop out and buy a kilo of peppermints for a start. But better yet, how about investing a bit of cash in this Topland Etiquette Checker? The tiny device contains some clever sensor technology which deliver an instant verdict on the state of your breath within seconds. Just breathe softly into one end, and wait. The thing has two modes, the first for dodgy breath smells, while the second will tell you whether you have too much alcohol in your aura and therefore shouldn’t even think about approaching your car.
