Don't rely on brutally honest little kids and loved ones to tell you when you have bad breath — let technology do it for you!

I have no idea how this Halitosis Detector [1] works, but it's definitely appealing to my deepest insecurities. For just $11 (on sale from $25!), this little gizmo somehow measures your breath in four different stages of stinkiness.

I'm guessing the horrified icon screaming, "Wait!" on display is the worst. What do you say, use the covert breathing-into-your-hand trick, or would you trust this gadget [2] to have your back?
