I do not know much about this "new" product advertised in TV, but when I lived in an apartment above others who "raised", or seemed to, cockroaches, a friend gave me a "box" that plugged into the electric socket, but instead of sending something through the wiring, as this new one states, this 3"x3" box, which looked like a tiny "speaker", simply made a "clicking" sound, ..no particular beat, but like a miniature "Geiger counter"! It quickly took care of the "bug" problem, w/o hurting the fert`s ears. It wasn`t that loud, hardly detectable when 6 foot or so away by humans. I haven`t seen one since, but maybe someone else has had one!?... Hope that helps...... Dooks to all,....John Rich & the n.j. gang of '1', USA. john rich <[log in to unmask]> [Posted in FML 5948]
