Review on Twinkle Star C6 Christmas String Lights, 100 LED 33ft Fairy Lights: Indoor Outdoor Decor in 8 Modes - Multicolor by Debbie Wells

I like these lights except. I ordered 6 string lights in October and 5 strings in November. The October order had Intertek LED controller #5015236 and the November order had controller #3140710. Original controllers can be set to "permanent" and will retain that setting each time you turn it on. Controllers purchased new in November do not retain a "permanent" setting, instead reverting to a "combined" function (no memory function) every time they are powered on. I replaced the new controllers with some of my additional previous controllers as you only need one controller to control five fairy lights. Without the memory function I would return this item.
