The lamps we ordered are attractive and generally well made.  They have a heavy metal plate in the base to keep them steady and straight.  The base has raised flanges or feet on the plate that are not coated with plastic so you have to be careful not to slide or rotate the lamp on a floor that might scratch.  The sockets are serviceable, though not best quality.  The bulbs screw in with lots of friction, as if you'd cross-threaded the bulb on insertion.  Also, if you screw the bulb down too tightly the light can't be turned off at all, so you need to be careful in seating the bulb enough but not too firmly.
