This is lightweight, functional and versatile. We use it when we travel to relatives and in the back of our van to keep both our (small) dogs safe and in a familiar space when left alone. One of dogs is blind and this pen is always set up the same in unfamiliar places. It has a handy treat pocket and water bottle holder. There are doors on both sides for easy access and the top is removable. We like that it can sit in a circle or bend to fit where we need it to. All the materials and zippers are working great. Easy to fold up with an elastic keeper and carry case and very compact and lightweight. Also, it's easy to pack. Worth our investment for safety and piece of mind as it has allowed us to travel with our dogs frequently.
