Not a lot you can say. Wanted to upgrade my Dell 620 from 512MB up to 2GB, so ordered two of these - I think memory upgrades for the Dell must be done in pairs. A word of advice if you are thinking of upgrading your Dell Latitude. One memory card fits easily into a bay secured by just one screw on the back of the machine. The other fits under the keyboard, and requires the removal of the keyboard. This is not as hard as you might think, BUT you must follow the instructions on how to do this, which are available on the Dell website. You won't need many tools - couple of jewellers screw drivers, plus a thin bladed knife.
Whole job should not take more than 20 mins.
