Can unfortunately only agree those who are disappointed. I had ordered a chain and out of the box made a functional test. At least 5 LED were defective. The conversion was seamless. Unfortunately fell in the new chain after 2 days 2 strands completely and had even directly next to each other, so that the very caught my eye when the chain was in operation. Conclusion: Price was great (had obtained in other markets comparisons), but what good is the price if the quality ones is wrong.
