I use this product mainly as a go-between to take pictures from my DSLR and put them on my pc. This eleviates the need to plug my camera directly into the pc which uses battery life and is generally a bit more of a faff. With this product it couldn't be easier, you simply pop the compact flash card in then connect the unit to your pc. You can then use it like any other storage device and simply drag and drop whatever you want off it into the folder you want on the pc. The transfer is very quick even with large numbers of files and the plug and play feature means you do not have to mess around with extra software or anything like that. I have not experienced any problems with it so far and it is an absolute joy to use, it is also very lightweight and easy to store away when not in use.
