I bought 4 of them to make a big pen for my 3 little dogs (Toy poodle, Maltese, Shih Tzu). I like this better than a real fence, because I can move it when I want to, or fold it away, if I don't need it. The set up was easy and I did it by myself. I got it hooked to my porch with wire, so I just have to open the door and let them out. That is why I did not get one with a door. It looks very stable and even so my yard is not that level, it works really great.
