Why it's a buy: Free your hands with this mask with a built-in 8-megapixel camera.
The device has just two buttons: the on/off switch, and one that snaps high-quality pictures -- or records standard video footage -- at up to 15 feet below (a light appears in your periphery when the camera's ready).
