- As soon as I rename folders on the SD card, they will become illegible;
- I can not put more than a certain number of files on my SD card, otherwise do not have access at the reader;
- The title changes aps pieces are taken into account when I make.
Note that I used both an SD card of 16 gigabytes ... and I never had any problem with my previous SD card reader (available from Philips).
Conversely, the big advantage is the autonomy! the battery lasts a number of hours before requiring a recharge is significant.
