Negative Positive
Title: Works as advertised
Review: I was reluctant at first about any ultrasonic pest controllers so I purchased this one due to it's three pack value. We live in a two story triplex and the neighbors brought cockroaches with them. After about a month of use we have noticed a drop off in visible roaches. We still see one once in a while but not as frequent as before. It seems to be working. We have cats and a dog also that aren't effected by this product at all. I would recommend anyone with pests to at least give it a try.
