The double door feature is a big plus. Makes access in cars and confined spaces much easier. Portability (folds up & is light) can be a big plus. If you are or will be into showing the access and portability are very important. Some comment on the light construction, but your crate should NOT have to restrain a dog who is bent on escaping! Crate train your puppy from day one and he will LIKE his crate and consider it his refuge. If you're trying to crate train a large, strong older dog, start with a more secure hard crate. Never use the crate as punishment! Your dog should LOVE to go in his crate and will voluntarily go in when things are crazy or you're using the vacuum, etc.. Be sure your crate is big enough that your dog can stand up fully w/o ducking his head!
