What a difference!!
Review by confirmed purchaser
My son bought an e-systems laptop which came with 1gb of ram memory. He complained about the slowness of windows vista even with very few programs on the hard drive. After checking with Mr Memory I found it would accept 2gb max on one stick of memory. After ordering, it arrived within three days very well packaged and has made such a difference to the laptop. He says it is now a pleasure to use.
