Query: DO NOT WASTE YOUR MONEY!!! IT DOESN'T WORK (VIDEO PROOF)

This thing doesn't workk! I even have brand new batteries in it, with the range set to maximum.We have a problem with a cat that is peeing where the previous tenant's dog did his business. We got this to keep our cat away from it. I set the item dead center in the area, fully cranked up on the range to keep her as far as possible. Guess what... She's still pissing!!!Here's a video: awe... they removed the link, so here it is spelled out www dot audronis dot com slash missy slash MissyPissy.htmlAt 15 seconds she enters, at 50 seconds, you can see her stroll right by the thing, and at 58 seconds, she does her business... RIGHT NEXT TO IT!!! Completely unphased!It's tight on her, making contact with her skin, and doesn't deter her AT ALL!!!I seriously wish I could not only return the thing, but have them pay ME for my trouble!!!
