We purchased one of these lamps for a whole-home design/build project for one of our clients, and while the lamp is beautiful, the cord etc is quite ugly.  Whats not shown in the product photo is the large bulky dimmer thats located a few inches from the lamps base.  Even though the dimmer is made from (somewhat) clear plastic, the beautiful colorful base is translucent, so you cant help but notice the large bulky dimmer being so close to it. 

A much better option would have been to use clear lamp cord, (not white) and a dimmer thats located just below the bulb, so it would out of sight.  Both these features have been incorporated into many lamps over many years and they work well and are inexpensive.  I plan to have my local lamp shop rewire this as I've described so we don't have to return it.  I realize doing so would void the warranty, but its worth it imo.

Pros: Colorful
Cons: Ugly, bulky, visible dimmer
