I followed the advice of various rave reviews and we must recognize that this lamp in addition to being aesthetically pleasing and good enough. Nevertheless it seems that I am an isolated case and all the better: because when I set foot in the arm with nut, I noticed that a game continues between the arm and the base at its junction . This game gives a slight instability at all rather unpleasant to use. So I plan to repeat this model and returned my purchase immediately in the hope not to encounter the same anomaly. Many greetings.
