So we use this chain now for almost 8 weeks, and unfortunately the weather was not always optimal. Some wrote here that it all night lights even with little sun. Unfortunately I can not confirm that but. For us it is almost never shone, even though we actually have sunny side. However, as already mentioned was not always the best weather. Once the sun all day was she shone reliable. But only then. So I would strongly recommend anyone to whom it does not matter if it sometimes for weeks or just a few hours very weak or flickering lights. From me there is therefore only conditional purchase recommendation.
