Before purchasing the item I had a question which was answered, via email, within 24 hours.  The delivery time was favorable and packaging fine, however, there was a small defect in the glass.  The replacement came quickly and was flawless.  I purchased this solely for the shade - as it matched the size and shape of a light  in my house that a contractor accidentally broke - so cannot comment on installation.  My interactions with customer service made this experience positive.

Pros: Customer service, light shade material
Cons: Defect in first item received
