Title: Does Not Work
Review: I purchased these products and installed at several places where we noticed mice droppings, hoping to finally get rid of these unwanted guests. These had been there for weeks now and still we're getting visits from these pests. So I put in glue traps that worked better as they caught these vermins one by one. My advice: Don't buy these so-called ultrasonic devices. They don't work!
