I bought two of these to replace old shades that are on nightstand lamps.   They are perfect; however, that's after they first spent about 5 days in the garage to air them out.  Right out of the box they had a very strong chemical  odor.  Because they were packaged with the manufacturer's contact information, I was able to find out that the shades are made and shipped on the same day, so what I was smelling was the glue.  I was advised that with some airing (outside the house) the smell would dissipate and it did.  Love the clean lines and color...so in spite of that little hiccup, they are worth 5 stars.
