This is beautifully functional in that it is no bigger than it needs to be. And a huge improvement over the old 30-pin connector. But it's also tiny enough to lose with ease. I'd like a small keyhole on it to thread a keychain loop through, or perhaps a case that has a keyring attached.
This little accessory saves me from carrying many cables around. Now I carry a micro or mini USB cable and cannect this and ready to charge anywhere there is a USB connection, so long as the cable is 36 inches or shorter. My 6 foot cable will not work no matter which direction you plug the bug in. Minor drawback is that it is so tiny and can be lost or misplaced easily. I keep mine attached to a cable or connected to the phone.
This tiny item is just the thing for charging your Lightning-equipped iOS gadget from your old micro USB charger. It works perfectly and adds virtually no bulk to the charger cable. Still, $20 seems like a lot, even from Apple, for this adapter.
