This is the iGear iGuard 2.o. This is a great alternative to guarding a room in your home against any kind of creepy crawler pests. Just simply plug it in and that's it. It lets off ultrasonic waves that drives those pest crazy. Do not use if you have rodent type pets, but you can use for everything else! Great to have in every room. I give this 5 stars. Please note I did receive this at a discounted price in exchange for my honest unbiased review. I purchased this unit on Amazon.com
