I also purchased this port replicator only to discover that it does NOT fit my T43. Product description is incorrect. Beware.

Warning! I ordered one of these and it was not supported for my IBM Thinkpad T61 Even though the advertisements states T series. So be very careful, make sure you verify that this will work on your laptop before you throw money down the drain. I learned my lesson. It is probably going to cost more to have this sent back than what I paid for it.

I bought 2 of these docks for use with a couple of IBM laptops. The advertising said compatible with R series Thinkpads, but they are not. Lucky for me they are compatible with my other IBM machine, so not a complete loss.
