Most delighted at the service, price and availability. I have an old Sony Vaio 505 that I had bought in the USA and had put Viking memory modules in, seven years ago. That memory failed recently and I was about to scrap the computer... where in the world could I find new, OEM certified memory at an affordable price? The answer was RamCity and Kingston Memory. I am delighted and my "little old Vaio" is eternally grateful.
