Quote from svp website:"Please Note: These are refurbished SanDisk memory cards which means they have been returned to SanDisk from retail outlets, tested by SanDisk, and deemed to be in perfect working order. It's not possible, as far as we are aware, for SanDisk to repair a card that isn't working so we can assume that all of these returns are either the result of user error, incompatibility with the hardware purchased or damaged packaging. The end result is that they represent the cheapest possible way of buying the popular SanDisk brand of digital storage. All cards come with a full 12-month warranty, exactly the same as if we were selling a brand new product.
The SanDisk Ultra II range is the high-performance digital memory solution for serious photographers. This family of outstanding flash cards provides the durability and high-speed quality needed for advanced amateur photographers and photo enthusiasts.
