The quality and ease of use are really outstanding! It folds up easily and neatly and is easy to store.  Our mellow 20 lb cocker spaniel did very well in the small size. The net windows allowed for cool breeze to circulate. Our high energy 12 lb jack russell terrier was able to unzip the front flap which might not be good if you are keeping your dog in the crate for safety.  Overall this is a fantastic crate...and the price was unbeatable.
