One of the lamps was extremely wobbly on my nightstand.  I placed it on the floor and on the dining room table to make sure it was not my nightstand.  There was over a 1/8" gap between the bottom of one corner and whatever surface the lamp was on.  I could not get the lamp shade to sit straight either.  Seems one lamp was "warped".  The other lamp was fine, but I wound up returning.
