My recent order for 2GB RAM cards was recieved on time, the installation was easy (took about five minutes to install), and the product works great!! If you are thinking of replacing your PC because of sluggish performance, I suggest that you seriously think about upgrading your current system. It doesn't cost an arm and a leg, and if you're a handy person, you can have your system working better than it did when it was new for a fraction of the cost. Thank you Crucial for breathing new life into my PC!!!
