Our neighbors had one. Works well if you train your dog.(Unless it gets up a head of steam and runs through it fast.) The problem with them is that it doesn't keep other dogs out of your yard and away from your dog. My neighbor had the collar in her pocket and forgot and went to get her mail at the curb. She walked through the invisible fence and thought she was having a stroke!
I'm not as worried about other dogs getting in (although she's still only 30 lbs so coyotes might be an issue-but she should get to be around 65-70 lbs) but I'm worried about her getting out. We live by the RR tracks too-so that's a concern. We're not the type to leave her out for long periods of time unattended, but it would be nice to know that we don't have to worry.
The fence works well if your dog is calm and heeds the beep and the shock. However, if he gets excited by a squirrel or something else, the faster they run through the fence, the shorter the shock will be as a deterrent.
They work in keeping yur dog within boundaries, but I don't like the concept. If I got zapped everytime I went somewhere "outta bounds"...I might start biting people or become a real wus who jumps at my own shadow.

I'm not at all a fan of invisible fences, as I think they are impolite/inconsiderate to pedestrians who do not know whether or not your dog is restrained. I love dogs and am not afraid of them, but it can be quite disconcerting to have a dog run at you barking - with no owner in site and no barrier between it and you.
There is a house at Sunset & Turner that has one of these. The first time the wife and I took Jr. on a bike ride, he dumped his bike and freaked out when the dog came within 1 foot of the sidewalk, barking in his face...
