I cannot fault the service I received from MemoryCow in any way at all. Throughout the process of initially ordering the incorrect RAM for my ageing laptop to it sitting on my desktop"firing on all cylinders", I was treated courteously,patiently and knowledgeably to identify and speedily supply the correct components which have revitalised my laptop. The order procedure was simple and customer support first class, I will certainly use MemoryCow again and would definitely recommend them to others.
