Review on 🎄 Lyhope Battery Christmas Lights - 33ft 100 LED Waterproof String Lights, 8 Modes, Battery Operated for Outdoor & Indoor Decorations - Xmas Tree, Wreaths, Holidays (Warm White) by Michelle Hooker

It's great! My kit lasts about 10 days or so on 4 new AA batteries. The timer is automatic, you can't set it or see it, once you turn it on it remembers, I think it was 6 hours on / 18 off. There are several models, according to which the light is on / flashing. I also bought a set for Christmas! 1st photo in the dark, 2nd photo at dusk. Like some others I made a mistake with the batteries, the double A's sit in a separate piece but this piece MUST be connected to the battery case cap which looks like a 9 volt connection. When off, the bulbs are clean, the wire is flimsy and tangles easily, but overall it's fantastic!
