I bought 6 pieces of this item 4 months ago. They worked fine at first, but now, after just 4 months, not 1, not 2, but 3 moving heads are defective. One has a motor (pan) that no longer works, and on the other two, the red LEDs have stopped functioning. Very unfortunate—one defect can happen, but when 3 out of 6 lights show defects after only 4 months, there is clearly an issue with the quality of this product!
