Bests & Worsts Reviews from Amazon

I purchased two of these because of the size of area I needed covered in my backyard from rabbits. The units had ZERO effect. I became so desparate, I placed BOTH units within 7 feet of where at least one rabbit would congregate daily and eat and urinate on my lawn. I look out of my window the next day, and there are TWO rabbits in the area, and these units aren't having ANY effect whatsoever. They are worthless. I'm about to process my 30 day money back guarantee NOW! If it works...it sure isn't on rabbits. WORTHLESS!
