Anecdotal proofs are compelling but mean almost nothing. These electromagnetic devices are not new, but it is amazing at how the claims purport to repell rodents, insects, and everything else while being harmless to people and pets.. I repeat my appraisal that if you want to throw away your money, you are welcome to buy one of these useless devices. They do nothing and there is no evidence anywhere to prove that they have any useful effect, other than the promise of unimaginable successful control of every pest under the sun. Good luck... by the way I am a Board Certified Entomologist and work in this field. I am always looking for better methods and approaches to pest management. I would be delinquent if I didn't warn consumers about this kind of useless product. Wonder who the outdoor living enthusiast is..?
