I bought two strings to my shop and my small windows. Good packaging, cardboard outputs one of the two garlands one "flower" had fallen to the bottom, easily handing the two garlands operate in series. All LEDs work. A command is coupled to the wire with a single push button top with 8 programs to choose from. The first carries the other 7 and again. This is the one that is programmed to the first installation. For now everything is working for 5 days / 8 hours per day.
