Query: Not very good

This product might be worth $5, but not what I paid. The arm is too short to be useable, I've already broken the switch (REALLY cheap) and all of the LEDs don't light all of the time. The head of the unit weighs so much that the base of the light stays loose in the power outlet - you have to hold both ends for the light to stay on.
