This lamp suffers from design flaws:
- The base of the lamp is not heavy enough to make the lamp balance when the arm is in a position other than aligned forward (hence the complete uselessness of this flexible arm)
- Used as a desk lamp, the batteries discharge very quickly, which is surprising for a low energy lamp,
- When the batteries are at end of life, the lamp will blink unpleasantly.
For my personal use, I think point me to a more expensive lamp and powered by the mains. If you are not too demanding, this lamp is perfect.
