The cable is good. Surprisingly came quickly, about 2 weeks. Someone in the reviews wrote that this cable works data transfer => this has become one of the criteria for choosing the name of this cable, but, data transfer does not work here. Did not guess to look carefully the characteristics specified by the seller, on the product page and there clearly indicated that not support data transfer. About charging, charging quickly, bought for rn4x snap. Charging speed with default wire is 1200-1500 ma, with this 1600-1700.
