Too unpleasant to use
on September 20, 2007
The product may or may not work. I do not know the answer because the side effects were too unpleasant to leave it plugged in for long. The frequency range it claims to operate under is well beyond what humans can hear, but the unit additionally makes a piercing high pitched whining worthy of making ones ears (and eyes!) hurt. It was certainly well within my range of hearing. I could hear the sound throughout my house, regardless of how far from the unit I walked.
Also having researched many models and brands of this product before purchasing, I felt comfortable in its reassurance that domestic animals would not be affected by this product. (Most similar products make this claim.) For this unit however, the promise turned out to be outrageously false. From the second the product was plugged in, my cat responded as if being attacked by auditory ghosts: crouching low to the ground, defensively spinning, darting about the house, dodging in random directions and doubling back on himself... seemingly unable to escape.
Within 20 minutes of receiving the product, I had already packed it back in its box and was standing in line at the post office to send it right back.
This product may deter pests, but it will also drive off family, friends, pets, and quite possibly your sanity.
I'd recommend looking into similar products with a higher price tag.
