I had been watching these lamps--I ended up buying two--for quite some time before finally pulling the trigger.  I am very happy that I finally did decide to buy them.  They are large, heavy, very substantial lamps and look absolutely stunning in our room.  The color of the lamps changes throughout the course of the day depending upon the amount of sunlight coming through the windows.  Sometimes, they actually look a really unattractive gray-black [or even brown color] when you look at them.  I'm not crazy about that feature of the lamp, but that is just a natural characteristic of viewing a glass product in different lighting and I can deal with it.  Probably the one thing about them that disappoints me greatly though is that they are huge dust collectors.  They're like magnets actually and I have to dust them off daily, which is both disappointing and inconvenient.

Pros: large, heavy, beautiful
Cons: dust magnets
