This is totally worth the money. I have added mine to my keychain. Now I don't have to worry about my iPod running out of charge.
The cable is very short so it may not suit everyone but it works perfectly as an emergency data cable.
As with some other cables I have bought from this website, I am going to order some more to add to my handbag, the car keys, etc.
Now if only MiniInTheBox could come out with a lightning connector version of this, my day would be made.
Update - July 15, 2013 - I ordered a second piece and received it today. I am very impressed by the delivery - reached me 1 week after shipping date.
