It was tedious to put together. When I put my dog in the first time, he broke out of it through the door because the door was easy to bend with light pressure against it. We had to put a cement block on the outside of the door to prevent that from happening again. Then he broke out again by popping loose the zip ties and bending the fence to create an opening.  The material used is of poor quality and not strong at all. I have a 45 pound, 7 month old puppy (pit-lab mix). This was a total waste of money.
