I have one, and I think you have to appreciate what it is that you have. Everyone is right--the fence doesn' t stop other dogs from coming onto your property, and if your dog breaks out, it keeps him from coming back.

I think the way to use the invisible fence is NOT as a regular fence, but as a " secondary barricade." In other words, if you expect the invisible fence to be as good as a regular fence, you will be disappointed, your dog will learn to break out, and it will be useless (unless you have a lap dog.) But if you use it to let the dog out for limited, semi-supervised exercise/activities, you will find the invisible fence works really well. In other words, if you expect you can leave your dog in the back yard for 10 hours while you go to work, invisible fence is not the answer. But if you use the fence to let the dog out for 10 minutes to go potty, or if you have the dog out in the yard with you while you' re working in the garden, and don' t want to watch him/her all the time, it is a good tool. As far as Invisible vs. Innotek, I dunno. I have one, cheaper that Invisible Fence, but not Innotek, I don' t think, but I can' t remember the brand name.
