Bought this to transfer files from an M2 card, and under the photo there is of course a port for M2/microSD. Just discovered that it is no longer correct - support for M2 has been removed. The door is a little bit lower so the M2 does not go in, and now it just says MicroSD on it.
No idea when this change was introduced, but it is made in 2013.
The card format here on-hunting was allegedly supported was also greatly exaggerated - this reader only supports nearly half of those formats. I've done an update of properties to reflect this, and hope it will emerge shortly, so that no more than I get duped.
