Set up was easy, seems sturdy enough, if there’s nothing in the shelf super easy to knock them off. Only problem, and It’sAnd big one.: first time opening the vents(windows) the Velcro rotted apart from the plastic. You would have to hold the back Velcro at the bottom and carefully pull the front piece away from it to get it apart. Happened in the door too, where the zipper meets the plastic. Wouldn’t recommend
