I love this lamp but the reasoning for low rating is over its quality (plastic piece to hold light bulb and shade was broken along with a tear in the shade upon arrival). My husband glued the plastic piece to make it work, have a claim in for a replacement shade.  Other reason for low rating is over the shade itself, it is absolutely gorgeous when not lit but once you turn it on the shade is completely see through so you see every detail of the light bulb and lose visual of the copper exterior.  Very disappointing! May try to line the interior of the shade to make it work as the lamp is beautiful...however, not sure if it is worth all the work in the end.
