Used, but for a few days. Could not return because of no receipt or box. Way too big for our small dogs. It comes with a crate divider which we thought would be good for our two pups but we ended up just getting them each their own crates. The crate divider is intended for a growing dog that will be pretty big full grown. So that you can make their living space smaller with the larger crate and give more space as they grow. Side and front doors with sliding latches. Foldable. Portable yes, but again heavy duty and HEAVY. Dimensions are 31"" tall, 28" wide, and 42" deep. 4x6 frame just for size reference. I am 5"4 and crate is up to about my hip.
