Review on ❄️ Enhance Your Décor with Product Works' UltraLED Battery Operated Snowflake Twinkle Light String in Pure White - 3.5 Feet of Mesmerizing Brilliance! by Becky Taylor

Small chain requires 4 AA batteries. The case is very thin and definitely not waterproof. I bought these to add to my porch wreath but I doubt they will last long and the battery compartment is too big to hide. The color change started in sync with red, then green, then blue, then shaky. We had one or two that didn't catch up and then everything changed. They're nice to look at now in all the different colors, and they're very bright. You have the option to make them blink, but the color change is permanent if set up without blinking. Nice, but I doubt they'll survive!
