These are gorgeous. They were pretty tangled up when I bought them, so at the end of the season (to avoid having to go through the de-tangling again), I used cable ties to keep the vertical strands separated. Unfortunately, a year later, the lights didn't work, but it might have been because I dropped them. Not sure what happened - maybe they're all interconnected electrically and a single bulb burned out. But read the specs to be sure. They're lovely and I'm ordering them again!
