Beautiful lamp, provides right amount of ambient light for my living room.  Seems quality and substantial.  Base is extremely heavy and while assembly was simple, it was NOT easy because of the weight of the base.  Was very hard for one person to hold the base and try to attach the lamp - would be more helpful if the insertion point was longer.  I assembled once and it wasn't stable, started to tip over and had to disassemble and start over again.  Second time I got it right, but I ended up getting some scratches on the base just from trying to maneuver the parts to assemble. Like the diffuser but it doesn't sit level, I had to put a piece of paper between the screw and diffuser to level it off - minor but annoying.  All in all, I like the lamp and it does the job, hope it holds up.
