I join the opinion of Mr Gass Alexander: indeed offer intérressanse on paper, but in reality it is a disaster, the cable does not work at all! Along with the same product in other colors, the comments were certainly mixed, but it seemed that the product worked. Apparently not ... blue. Certainly this is not a heavy expense, but still ... the consumer is entitled to expect a product in working condition. Conclusion: do not waste time or money, and you turn elsewhere.
