The lights worked when I first received them. I left them in the sun to charge all day and they sparkled beautifully come night time. I then set them up - wrapping them carefully through my deck banisters, and now - nothing. Was it 1 day in the elements of the outdoors? Or is the wiring just garage? I don't know. Super disappointing, though. They would have made my patio look amazing. Obviously not well made, and definitely NOT for the outdoors - which is strange, because they're solar.
