Purchased 3 of these and all of them have some minor strange rust or dark staining on shade trim (top and bottom) The spots are small though so once installed on the ceiling there are not very noticeable. I just kept them since I really liked the style/price and we needed lights right away but I would select a different light if possible.
We had this lamp installed in the foyer of our apartment (note: we did not install this one ourselves so have no knowledge of how difficult or east it was to install). It looks great and expensive. It was slightly lopsided at first (did not appear due to installation: was inner and outer shade alignment), but somehow straightened out and now looks excellent. The one issue with this fixture is that the bulbs are incredibly hard to change -- docked one star for this. Normally I would say just buy LED bulbs and be done with it since they last years (decades even), but the light and fixture looked much better with incandescent bulbs. Still, a great looking light and I would recommend it.
Purchased for 2 bedroom that are rather small in size so they worked perfect for the rooms. The lights were smaller then I expected but I think they worked out perfect for the size of the rooms. Very fresh and clean looking. You may need to wash the plastic bottoms a few times because they collect dust especially in a construction zone.
