Simple, fast, straightforward to use--slide in your compact flash card into the Delkin and put it into your PCMIA laptop slot. You will have to install the driver for the Delkin, but that isn't hard to do at all. Download the driver from the Delkin site and follow the instructions.Regarding the speed for transferring files--whatever type of file you got(jpegs, movies, documents, etc...)-- it is drastically faster than the 16-bit versions of these PCMIA card readers, and about the same speed as USB 2.0, more or less. I had bought a 16 bit PCMIA compact flash card reader(made by Sandisk) prior to the Delkin purchase, and comparing the speeds of both, Delkin took less than half the time the Sandisk took to transfers files.
