Great product for my very tiny Yorkie. I purchased the smallest size crate, and used the divider to make the space a little smaller for him as a puppy. He won't need the divider any more in a few months and then I'll take it out. Easy to assemble, and works great for sleeping at night and crate training. My only complaint is that the handle doesn't fit between the bars on top correctly, so I don't use that.
