i purchased 2 of these lights. They came at different times. The first light worked when we plugged it in to try out. aA week later it only worked upside down and only a small radius.The second light came around the time we were ready to decorate. This one the inner mechanism would shake when it was moved, as if something was loose inside. It gave a feeble tiny light then nothing. I purposely chose a model that was priced not too low and not expensive, not willing to spend more. Definitely not satisfied.
