bought 4 of these for christmas presents, and one for myself. each family member has reported the light stopped working after a few uses. one went out when light was set down on the table , one was dropped on carpet , one went out while being held and used in someone’s hand, and the last just ‘didn’t come on’ when my brother went to use it one day. i still have mine sitting on my desk (haven’t used it yet) and i’m afraid to pick it up. apparently they are really bright and work really well as long as you never touch them.
