I bought the extra large size for our two dogs. Setup was easy but the wire isn't as thick as expected on a crate of that size. It's not really sturdy enough to stop the dogs if they feel motivated to get out of the crate. For what we paid, it wasn't worth spending the money to send it back. We'll keep it as a spare or give it away to someone whose dogs don't mind being kenneled as much as ours do.
