I just received my lamps.  They were easy to set up, and look very nice on each end of my couch.  They are smaller than the ones I replaced, which I really like.  To me, the are different looking, modern, and yet classic.  The slate is heavy, so your table needs to be somewhat substantial.  The plus is that they will not tip easily.  I am also happy with the shades, both the shape and the fabric. I wanted lamps that used a 3-way bulb.

Pros: Good price for table lamps, easy set-up, very pretty and distinctive looking. The multi colors of the slate will allow them to pair with all types of metals in the rooms.  They arrived in a timely manner.
Cons: Not a problem for us, but they are heavy.  This should be a consideration before purchase.
