This was a very disappointing purchase.
Most of the "stained glass" is actually plastic. The plastic collars which screw-clamp the shades to the fixture base do not fit the threading at all, they float over the threads and because the threading doesn't extend to the base, the shades can't be securely tightened. Despite being described as an "art nouveau bronze", and appearing so in the product image, the finish on the fixture was actually a deep, unattractive Puce, with no hint of metallic finish. To match the rest of the bathroom fixtures the unit had to be treated with a faux finish.
I found no evidence of the fake stained glass being "wrapped in fine copper foil" - rather the plastic shade panels seem separated by strips of good old fashioned lead. Handling the shades leaves fingers covered in a leaden film - I did not see a Lead disclaimer at the time I purchased the unit, although I do see one posted now. The "four (4) 60-watt light bulbs" needed turned out to be G-Type, which was also not disclosed on the product information page.
Finally, the mounting screws provided would not thread into the existing electrical junction box.
In summary, this unit was not as described or as pictured, features inferior construction and materials, and needed many hours of extra work before it could be mounted and used. Had it been possible, I would have awarded zero stars for "Ease of Assembly". Product value as received is far beneath the purchase price, although the appearance and function of the unit post-modification does live up to the expectations of the purchaser.
