We bought the fairy lights a week ago and, since it goes on to Christmas, decorated the balcony so immediately. You can actually do anything wrong. Place where you like them, turn on, finished! Worked immediately without any problems. Also brought out of the box, it has been lit .. and until the next morning. But the next day, then, when the sun was not really so very seemed and the chain thus little opportunity had to refuel, the initial joy subsided quickly. When darkness it shines even prima, unfortunately leaves the then very quickly and after only a few hours doing nothing more. The 2-3 hours, then the time came out the sun during the day, have helped not much. Conclusion: For the summer sure great to somewhere suitable to conjure ne nice atmosphere, but in the winter as Christmas lights rather less.
