We purchased a home and remodeled it as it was in disrepair. We love the location and have wide open views however there was one problem that was left unattend by past owners, RATS! They did try without any luck to rid the property of rats, as I found many old wooden traps. I tried EVERYTHING out on the market with no luck, when a friend told me about the RatZapper and let me borrow his. The first night his RatZapper executed 4 unwelcome vistors, RATS! Quick, Clean, Humane and Easy which made me not only a believe but also someone that wanted to own one, so I bought one the next day! Now I have my own RatZapper, nickname Little Sparky as in the electric chair, and have had success cleaning up a problem that was not very pleasant to deal with. I am a true believe in this product.
