Review on 🎄 FULLBELL MultiColor Christmas Lights, 72ft 200LED Indoor String Lights with 8 Flash Changing Modes, Waterproof USB Power Wire lights, Fairy Twinkle Decorative Lights for Patio, Garden, and Home by Lisa Fernandez

The advertisement says "8 different flash settings". My only real complaint about these fairy lights is that I can't choose which sequence I like best. They work on a whim with different flash settings. Many of these fairy lights have a knob or knobs that allow the user to select the lighting mode (fast blink, slow blink, fade in and out, etc.). Next time I'll have to read ads, comments and user questions better. So far, after a few weeks of use, they seem to be holding up well to the weather outside.
