I bought this cable on amazon and I am fully satisfied: - Delivery: fast and well packed - Quality: looks solid and load my iphone as quickly as the original cable. We will see how he will resist the passing of time. Anyway it is guaranteed for life. Note that I received a reversible cable without logo, which can be used in 2 directions (Like the original Apple).
In short: if you need a replacement cable as well and cheaper than the original, you found :-)
