Sending an alternate memory card because the original advertised no longer available (Discontinued) is. Spacious, friendly and highly informative expressed regarding response to my inquiry by email. The deviant delivery. Thanks to the detailed explanation of my concerns were resolved to use these memory card completely. And - what has become rare in our society - the "error" was added directly. Laptop is now running twice as fast. At last the long search for the appropriate memory card has an end. (First Company here at Amazon has not responded to my query and only refunded the money for the misdelivery.)
