This is awesome. 2m wire and perfectly working!! I strongly recommend it to charge iPhone on the bed while using it or sync/charging on desktop computer.
Good quality and fair lenght of the wire. Really cheap too :)
The extra long USB cable work good, the extra lenth lets me connect with the charging unit and to my computer that is under the desk much easaier. Also when I travel I now can reach the outlets in the hotel rooms when I charge my phone. I think the ones they give you with the phones are to short.
