We're sure that if most of us are being completely honest, we could've used this device at least once while we were out. It's a body odor checker that connects to your phone. Its official name is the Konica Minolta Kunkun Body Odor Checker, which doesn't really roll off the tongue. But it will quickly and seamlessly be able to detect whether or not you have body odor and how bad it is.
However, there is one pretty big drawback that we could see limiting the device's potential. It costs $450, which is an awful lot of money to spend on something you could probably just use your nose for.
