This keeps stick to its promise in terms of speed, data are transferred quickly. Although there are even faster models on the market that are in both directions almost the same speed, but must only times as chic and functional as this, and at a very good price. Locking the cap works very well and when accessing the stick lights a lamp, which is very convenient. All in all you can not do nothing wrong. Only the insertion is a little stiff, which is rather on the stick, an iPod cable is much easier in the USB slot. Therefore a star deduction, so Sony does not pick up. ;-)
