Negative Positive
Title: not effective pest control
Review: this seemed to work initially, but after about a month (and, not so coincidentally, when it started to get cold outside) i was finding mouse droppings less than a foot away from the device!i spoke with a veterinarian that specializes in digusting rodents (rats, mice, guinea pigs, gerbils) and she said that it's just like living next to the train tracks - it emits an annoying sound, but eventually the little suckers get used to it.
Is the review positive or negative?
