The lack of a universal charging cable is one of my biggest gripes as an iPhone user.
I never have there right combination of chargers and connectors with me on any given trip, so this $9 dual charging cable is a real boon.
Charging is easy. iTune recognizes my iPhone when I plug it in, GoPros mount instantly. The zipper for managing the loose cable ends is a pretty good idea and saves me from headphone-like tangles. All in all, I am getting everything I want out of the cable.
Charging 2 devices at once via my MacBook Air is not the fastest thing on earth, but that may be more a function of the port and then cable. I'll try it with a high speed charging port soon!
