Review on Needostar Outdoor Christmas Decorations: 317 LED Tree Topper Lighted Star, 8 Lighting Modes - White by Megan Hartman

The lights looked perfect for our outdoor holiday display but it took a while to understand the instructions. After finally figuring out the pattern we wanted (fixedly) and installing it, we were surprised to discover that if you plug the light into a switched circuit like a photocell or Bluetooth-enabled power switch, the light will revert to the first program the controller does, not the last mode selected by the user. In other words, you're forced to use a timer on the controller (6 hours on/18 hours off) and need to have constant power, otherwise you'll have to physically reset the timer and pattern settings.
