Sony Pro Duo Memory Sticks

I am really chuffed to find a reliable supplier for my Garmin memory cards after a couple of duff purchases from other suppliers. I understand the Garmin requirements are particular. Memory Cow actually checked my device type and serial number to match the correct card type. It was delivered swiftly and to much relief, worked perfectly. I shall use Memory Cow for all future purchases. 

All the detailed info in one place. Along with wikipedia, i was able to decode the engineering of the devices. What is missing? data sheets to understand programming requirements of the devices. 

Fast service at a great price. Thanks. 

Website and online information and guidance was excellent, ordering process easy and prompt delivery. Couldn't ask for more. Would recommend to anyone. 

Very fast dispatch and delivery, product was well packed and exactly as described. No problems whatsoever, I would definitely buy from them again!
