Product Review (submitted on April 13, 2009):

This is absolutely the best product for training both the neighborhood dogs - and their owners- to stop using my lawn as a toilet. We've tried asking, telling, video cameras, signs, bobcat urine, and the ultrasonic "cat stop." Nothing compares to seeing the offenders get blasted with water. The settings a very sensitive and precise and allow you to set this to blast exactly where you want and where you don't. By the way, its great watching the faces of your neighbors and seeing how annoyed they get that your property is off limits!
