I own 3 targets and this is the first one I can putt like Kevin Jones on. The base is heavy, the post is heavy, the cage and band are heavy. The chains are super heavy. I love it.
Mine did not come with any directions but it came with some extra screws and I figured it out pretty fast.
The best trick for assembly is to have a drill with the proper allen key "bit" and several of those bit-holders so that you can create about a 14" extension from the body of the drill that has some play in it. This will drastically speed up inserting all the little allen-screws.
I practiced my butt off on this basket right after getting it and it was about a week before I hit the course again and the standard baskets seemed generous and my putting had already improved. I keep it in the house and my wife is super happy about that. haha.
