I have not used the two cards received, but I've already ordered there ~ a year, and they function normally. By cons, in the "department store", it is stated that the xD no longer exist, you ..... by selling computers that have the xD connector on the front. I only regret that the port is charged twice while the two cards were in the same package and that their weight is not likely to cause overflow (I had just ordered 2 to split the cost of the port by 2).
