The next time you leave a room you don’t have to wonder what everyone is saying about you. You can simply whip out this compact eavesdropping device and find out for yourself. It looks a bit like the business end of a stethoscope, but uses an electronic internal sound amplifier to boost the noises coming through a wall, door, window and even steel plates. (So you can listen in on conversations inside a tank?) It’s rechargeable via USB and includes a set of headphones you’ll probably want to instantly dispose of, and is available from ChinaGrabber.com for $62.99.
