The problem with terrible breath is that you're always used to your own, so its hard to know when you've got a bad case of halitosis without subjecting a friend or loved one to a hot wiff of your inner winds to give you an honest response. And who wants to subject friends and loved ones to that?

Enter the Halitosis Detector, a wee gadget that rates your breath in four stages, from smelling-of-flowers to vile-sufuric-pits-of-hades. It's a mere $11 as well, which is a small price to pay for knowing when you need a breathmint to avoid coming off as a disgusting individual to others.
