When I receive the lamps one was in a new book that had not been open.  The other one was already put together and I never tried either one, until months later when I tried to turn the one that was all ready put together.  Of course it didn't work. Was not happy. T hat is why I didn't order for a long time.  You sent damaged goods to me.  But I ordered cocktail table and end tables which I'm very happy with.  Couldn't get over how nice they were. Thank you
