This is a very good product. The metal bars are fence grade quality and weight and the netting is okay. It was used tl introduce new chicjens to an existing flock. Once that was done, we refurbished it and it now works great as an add-on to extend an existing run, giving the chickens extra room to run in when they need space from each other. We have had it a while and don't see any rust. It was fairly easy to put together but you do need to wire the netting together. I wired it after I put it on the frame. It is heavy to move. I just put a tarp under the one side (so it slid better) and lifted up the other side to cart different places. It was missing one bolt but it was such a common sized bolt, rather than wait, I just got a bolt from the supply store so I can't tell you how quickly they would take care of that. The door goes together well but if the frame is not true, the door does not close well. It is easy to fix though.
