Notebooks all have a SD card reader, CF card reader can be found rarely.
To transfer images to a PC and parallel to use the camera had to be this adapter.
Works flawlessly. By the way, on television.
If you do not very carefully deal with the adapter kinks during insertion of the CF card before a pin from, since the guide rail for the CF card is very short (compared to the Camera). I have the pin grade bent with tweezers and some fumbling again. When I again need a card reader, I would take care, that the CF card is done a little better, so I break any pins.
