Arrived packed well in a small box, but still with a scratch on the hub piece. Arms’ wires are threaded but you put in place with an already threaded washer and nut. Little wrench is included to tighten. Very easy to assemble, easy install. Can take up to 60W x8, but I use LED equivalent, and a 60W bare bulb is sometimes hard to look at so I used 40W. Need to fix the ceiling paint, but I like the look. Can’t see the scratch.
