The LED charging light indicator is a missing feature of the iPhone (in my opinion), but thankfully this feature is built into this cable. The LED light is red when it's charging and blue when the iPhone is fully charged. Now I can see from a distance if the iPhone is fully charged or not, without having to check the iPhone myself manually.
I dropped one star from review simply because I'm not a big fan of the flat cable, I would prefer it to have a round cable instead – as with most other charge cables. But that's just my personal preference, others may prefer the flat cable.
