Consumers beware! I bought four CATSTOP untrasonic electronic repellant from Contech electronics based in Canada, and these products do not work. They did not do what they were supposed to do( prevent stray cats frrom using your garden and yard as a waste ground). Please consumers, do not buy these products from this company or their distributors.

The products do not work and this Canadian company has no human conscience! I called the company and they will did not take responsibilities for their actions. I have also reported them to the better business bereau in Canada. I cannot understand why a company like this can knowingly market a product that does not work.
