“The instructions for this were pretty much useless. They are very vague and the photos are not clear. With that being said, it was fairly easy to assemble everything up until the adaptor panel. (Adapter panel does not come with predrilled holes!) The run itself is quite sturdy and heavy duty. There are some larger gaps between the panels so keep in mind, it isn’t 100% predator proof (small animals could get through like minx, rats, snakes, etc) But overall, it is a decent run.”
