I have ordered 3 these light curtains and inserted for testing, everything worked. Now I have hung up and found that when 1 is missing a star and the other the power cord is only about 30 cm long, the lighting for 1st Advent. very annoying! I've now helped out with extension cord or a plastic-Star another string of lights. Had I discovered these two defects earlier, the order would have declined. So be careful!
