Title: Complete Hoax
Review: Ultrasonic pest repellers are a waste of money. While pests can hear ultrasounds that humans can't, even if initially frightened by these sounds, rodents will always realize the sounds aren't connected to any form of danger and will return to their feeding and nesting areas.Query their effectiveness on Yahoo! or Google and read for yourself.And lastly, your pets CAN hear ultrasound as well, yet they remain largely unaffected by these devices. Consider that.
