I bought this mobile charger from the Apple store on 10/2/2012 and as of 01/16/2013 it no longer charges. Ninety days later it doesn't work at all. It worked great at first and then nothing. Just be fore warned - it may not last as long as you think.
Both the car charger and the wall plug works well overall, definitely charges fast and looks nice. My only issue is that when charging an iPhone 5 with the wall plug the screen is inoperable. I can't swipe to unlock or start any apps if the phone is already unlocked. Unplugging the cable fixes the issue. Not a major problem but the reason I'm giving it 4 instead of 5 stars.
