I now report the USB stick only positive for about a week and can. Property me worried him to cut video files on a reliable and fast medium. 1GB avi video material was copied to about 35 seconds on the stick. Perfect. So speed 1a, processing as well. The stick makes a solid impression in spite of plastic and does not create the feeling, to break apart. Well thought-out system. Pressing the right side of the stick to the left, is the left of the USB port moved out and locked with a faint click one (hence probably the name?!?). While reads and writes an orange LED lights up right next to the words "8 GB" (which you then yes not see). The pre-installed software "Virtual Expander" is about 4MB. Removed but superfluous Read Me and presentation videos, then it is only 1MB in size. For software to be there is not much to say. Double-click on "Virtual Expander", a symbol settles on the toolbar and everything is copied to the USB flash drive is automatically reduced. A Word document, for example, from 28KB to 6KB. A video remains virtually unchanged, however. For this, the software is therefore only of limited use.
Conclusion: Unrestricted buy recommendation! Fastest USB memory that I have ever seen.
