Review on 🎄 33ft 100 LED Battery Operated Twinkle Star Christmas Fairy Lights – Waterproof Silver Wire String Light, Remote Control & 8 Modes – Ideal Indoor/Outdoor Xmas Tree Wedding Party Decorations – Multicolor, 1 Pack by Greg Harris

When we were decorating for Halloween I bought (2) these purple ones. It is easy to decorate copper with it. Set to a mode. Every time I turned the light off and on again the next night, the same light pattern stayed and turned back on immediately. I turned off the light as I went to bed. So you will work about 4 hours a day for about 3 weeks. Batteries never had to be changed. and the hulls were indeed watertight. Loved this product. The remote controls worked great.
