The first review of Compound Security's Mosquito device is in. The ugly little box works by emitting a high-pitched noise that only the younger folk are supposed to be able to hear. Trouble is, in Gadget Lab's test, the sound was audible to those of the older generations as well, those known to the food and beverage trade as paying customers. The risk is just too great that you'll drive the wrong people away from your teen-infested establishment, and besides, the thing costs $745. Best to stick with more proven cliches alternatives, such as Muzak or a broom you can shake angrily in the air.–Wilson Rothman
