This Micro USB Host OTG cable works exactly the same as the super expensive Sony Tablet S USB Adapter for Sony Tablet S USB. It should work with most USB Flash Drive, Mouse and Keyboard, but please note that some of them may not be compatible. There is not time lag of playing a movie file on my USB Flash Drive and it can be played directly with this USB Host Cable, it also work with external harddisk with Fat32 Format, BUT It need external power source for the harddisk. It should also work with non-power card reader.
