We don't sell fake or so-called "upgraded" product, all of our products have authentic memory capacity as set forth. At our practice, we will test the product before delivery. Sometimes you will see the files with the name 1.h2w, 2.h2w, 3.h2w, 4.h2w, ... in the memory card, don't worry and just delete them, they are the testing files left by the capacity test software--h2testw.exe.
