Query: New version needs some work...

The hitch I received did not have the twist knob to attach, just a flimsy piece of metal that wrapped around the seat stem and is held by a pin... as you can imagine, it was bent within a few days, and I not have to attach the trailer to my bike's pannier racks.If you can find something else to work as a hitch, I would go with it instead.
