Easy to put together, stable, spacious, tall, secure containment for my small dog. Visitors to my home complimented the appearance of this pen. Set it up in the circle formation with all 8 panels. Easy to clean, the panels can be easily taken apart, hosed off outside then dried in the sun. I don't have to worry about my small 20 lb. dog while I'm away from home, or any time I can't supervise him, or when deliveries are being made and the front door is left open. Big plus knowing he has room to move around while I'm gone. I trained him to get used to his previous Iris enclosure when he was a puppy by putting treats inside, toys, bed, food and water bowls, and gave positive encouragement and left the pen open for him to go in and out on his own. Just bought this new Iris pen in black. We leave the end open while we're at home and he goes in and out when he chooses. He is not confined in a black wire crate, ever. I have a travel kennel for trips by car but I don't own black wire crates as this enclosure is the perfect humane alternative. He's 7 years old now and these long lasting Iris pens have helped me and him have a better life.
