    I've recently upgraded memory in four computers.Picking a memory upgrade was easy and installation absolutely no problem. Performance has improved and reliability has been excellent in all four computers thus far.

              RAM upgrade worked well, was easy to install, and was reasonably priced. The product did take almost ten days to arrive, but I was not in a hurry so this was not an issue for me.

                    Just wanted to increase the RAM in an old notebook and this item did just that. Price was reasonable and order was received promptly. This wasn't my first purchase from Crucial and it sure won't be my last.
