Bought this crate for our Golden Retriever pup when we got her at the age of 2-months. The divider was nice because you could continually make the crate the appropriate size for a growing pup. The divider was fairly easy to move, sometimes a bit of a pain as the hooks (shaped like J's) would get stuck on the crate-wires while trying to move it. It's manageable, but something easiest done on your hands and knees inside the crate. Our Golden's now 6-months and we no longer use the divider. The crate is very sturdy and it's collapsibility is great for taking it from the house to the car. We liked it so much, we bought a second to replace the other crate we had.
