A bit more annoyed me that the enclosed SD card reader which is not shown, compact microSD reader, but a normal, clumsy SD Card reader (the figure has since been corrected). Even that is not a show-stopper for me, since I already consider the reader only as an extra. I can, however, easily imagine that this (shown, but not delivered) compact reader can be a decision-making basis.
Conclusion: Cheap microSD card if you do not have to claim this very fast read / write and the reader does not need for the keychain.
