Some years ago, after a particularly bad outbreak of bug bites, we purchased a $500 propane-powered mosquito-repellant system that was supposedly effective enough to be used by the military. (Is that an official gadget cliche yet?) We never got it to work, naturally, and it sits in a corner of the garage mocking us daily.
So we're somewhat dubious about any device that claims to eradicate the winged leeches unless it involves mass quantities of highly toxic industrial-strength pesticides. But this mosquito repeller claims to do just that with ultra-sonic sound in adjustable frequencies.
Please forgive our skepticism, but we can't help but notice that it comes from the same company--Hong Kong-based Brando--that gave us theand a . But hey, it's only $9, and it doubles as a lighted keychain. Once a sucker, always a sucker.
