The pen assembles easy and it is sturdy. Gate door works great and then we rubber band it open until we go away or go to bed for the night, then we shut it up and dog is secure. Can't wait until weather gets warmer then we will be taking it outside on the grass while we are doing yard work! Highly recommend this product!

Pros: Easily put together and very sturdy and attractive.
Cons: No complaints about anything. Love it!
