I am using this cable with the iPhone 5s.  From a build perspective, this cable appears identical to the cable that came with my phone.  The size the of the connectors and style are the same.  The fitment is also the same.  I have had no issues with the operation of the cable.  I can't speak to the durability, but I will update my review if I have any future issues.  I am pleased with this purchase and would buy from this manufacturer again.
