When this was new, it worked pretty well. I did have to use a bolt to keep it from wobbling too much in my hitch receiver.However, after about 8 months, it's too sloppy to use. There is a small round pin at one joint, that fits into a hole that is a bit too large, creating some slop. At the other joint, there is a square-headed bolt that engages a matching hole in a soft steel plate. Imagine using a wrench on a square-headed bolt, that doesn't quite fit, over and over. As you might imagine, both the corners of the bolt, and the interior corners of the soft steel plate, get so rounded that the step moves from side-to-side a good 10 inches when my dogs step on it. They don't like that, and my older dog has fallen a couple times.
