Well, it's not really my kind of writing comment unless I am really satisfied with the product or so incredibly disappointed ... This is not the first time that I am disappointed by cables "certified by Apple" ... So yes, this specification is proof of quality, however, it only works when it wants, so I question the Evaluation of Apple in relation to derivatives. Here, the cable might be half as expensive as the original Apple, but even plugged in, sometimes it does not load (while the cable was pushed in on both sides, needless to say). And worse, no synchronization is possible between my iPhone 5 (not jailbroken of course) and iTunes from my MacBook Pro. Great!
One tip, if you do not have a very high expectation of a cable, so take the expensive months. But if you are looking for something serious, go your way and opt for the official cable sincerely.
