We ordered two pens and were able to corral a large area in our backyard for our two wiener dogs. The sections are lightweight and it was easy to put together. We love that our dogs can now go out in our yard without a leash. On the downside, I read reviews that the fence rusts but decided it was worth the rust to have a fence for our dogs. We have had the fence up for less than a week and it is already showing signs of rust. But it is doing it's job and we will have to live with the rust.
