This flash card is an excellent way of adding an extra reader for Compact flash to your laptop. It works very well, so you might wonder why I didn't give it 5 stars. Well, it is very slow at reading, in fact, it's slower than using a multi card reader which you plug in with a cable. I don't know whether that's because of the card itself or the computer socket capability. If you have a full CF card to be read, you may be better off using an ordinary card reader but for the sheer accessibility and convenience of having a card reader in the computer, this is great and it was under 3 quid.
