This is a great product. Multiple uses. I use it in my car to transport my Cockerpoo and Poodle to the Vet.The top door feature allows me to safely place my dogs in and out of the carrier. The "garage door" allows me to place it in front of my doggy door. This way my puppy and older dog can go outside and inside to the create without getting into things while you are out of the house.When I come home I turn the create around (without my dogs in it). My dog likes to lay in there with his toys I gave it 4 stars do to the fact.  I'm concerned it can collapse when my puppy gets bigger, banging against the side.It could be sturdier and the clips are flimsy. Must be extremely gentle for fear of breaking.
