I tried this adapter in two different Lenovo machines (T400 and T400s) running Windows 7. Neither machine would detect the adapter or load the necessary drivers. I would return it but I don't have the packaging so I will just have to eat the cost. If you have a Lenovo T400 series computer, do not buy this adapter.

If you need one, you need one. I went back to using a USB cable for my Nikon D-300.

I had been looking for a way to transfer my photos from a CF card to my Dell computer. I had a USB adapter but it was too slow and I kept misplacing it. Now I can fit the adapter into the Expresscard slot and it stays there. And it was fast, fast, fast. I was able to transfer just over 200 photos in less than a minute! Before, this would take close to 10 minutes. And I have no trouble inserting the CF card. The adapter doesn't sit completely flush with my computer, but that's such a minor detail for me, considering how fast and convenient transferring photos have become. So glad I got this!

When you have the adapter inserted into the laptop's Express slot and you are then inserting the CF card into the adapter, when you go to click the CF card into the adapter pins the CF adapter pops out of the side of the Express slot thus causing Windoze OS to lose communication with the card's virtual drive map function. This can sometimes raise hell with the OS especially if you lose communication and them reestablish the link and lose it again three or four times before aligning the CF card into the adapter and then getting the CF adapter to click and lock back into the Express card slot. This adapter fits flush with the side of my HP laptop and probably yours as well. This is good because it turns a useless Express card slot into a handy, high speed CF card slot allowing pro photographers to leave the card readers and cables at home. /transfer speeds are faster than USB 2.0. So a 4GB Sandisk II card takes about 1.5 to 2 mins to transfer say 200 Raw images. That about 14 to 16 MB/s. That's about 1/3 to 1/2 the speed of say a Sata II internal to internal HD transfer running at about 35 to 47 MB/s. So it beats the pants off USB but be certain that this baby is fully inserted and locked into the slot before you start a data transfer. If this adapter pops out in mid transfer you stand to loose or corupt whatever files were getting transfered. Hopefully its not the cover shot that's paying all the bills that month.

The item took a bit more than a week, but worth waiting for. It flushes completely in my lenovo t400 and transfers data super fast. At first I thought i wanted to buy a Delkin brand, but I am glad buying this one, it works and my cf card slides smoothly inside the reader.
