Valentine's Day [1] is just five days away, and whether you have plans with your long-time sweetheart or with someone new that night, romance could lead to some smooching — which is no time for bad breath! You could cup your hands over your mouth, exhale and take a sniff, but why would you when you can use this bad breath detector, called the Kiss-o-Meter [2] ($30)?

Just breathe into the holes and wait for the five possible outcomes: Kiss me, Possible, Maybe, Risky, and Never. Tell me, do you think this is a useful tool, or would you consider the Kiss-o-Meter a gag gift you'd never buy?
