Nothing but good things to say, very concerned about the animals and guess what? That's what it's all about to keep them safe and it is. I have 2 dogs, one of them kinda dumb, honestly never thought he would refrain from chasing cats but this worked! I lost a dog a few years ago chasing cats, got hit by a car. The worst thing I ever had to go through. This is the nicest thing I could have ever done for my pets, although they don't think so, they are still a little scared to go in the lawn........decent price , great REAL people and excellent product!
