However, DX's memory card price seems to be too low and the photos in their website, the memory cards are fake. Thus, if you do not mind to get the fake one, DX should be your good choice but if you want to get the real one, try other store or you can try to have a look in our store.
The disadvantages of fake memory card are as followings,
1) The life of it should be shorter
2) The stability is worse than the real one
3) The data in the memory card may be lost without any reason
4) The shell of the card is bad so it is easily to be broken
BTW, if the memory card is the Sony memory stick, the situation of the above problems will be more serious.
