As some other reviewers have pointed out, this is almost certainly not an "Official Apple" product. However, it is much (much!) better value for money, and is of perfectly good quality.
It might be worth buyers noting though that on the version I received, the iPhone connector doesn't just loosely pull out of the device in quite the same way that the Apple version does. Instead, the connector has subtle buttons on the sides of the connector, designed to be squeezed when it is pulled out.
