Product review (2 stars): Works, for now, but not consistent.
Ok, so I gave these two stars, because I'm not sure how long they are going to work.  One of cables sometimes charges, but it consistently goes in and out.  The other cable works so far, however I did get a notice on my iPhone that said 'accessory not supported'. I unplugged and plugged back in, and it worked again, but I'm skeptical it will continue to work.

The metal piece on the cord looks different. There only one side has the copper/metal lines. The other side is smooth. (See pics). You have to plug in with the bars facing back or it won't work.
