T3-R Triple High Impact Mice, Rat, Rodent Repeller

I bought this and as soon as I switched on my dog started barking and became restless. I tried to position it in the garden, in the shed and my dog continued barking. Even when I pit it in the loft the same thing happened.I could not use it. I contacted the seller who was very unhelpful. I spent a lot og money and cannot use the item, which should have clearly stated on the box that dogs are sensitive to it.Be careful ! you will not get your money back as customer service is terrible. There are better erepellents and cheaper ones too.
