The card works well, I stay 2 micro SD 16GB each for a psp fat in 5.00M33, the PSP did not recognize at first, it is necessary to format the card, once you format if it displays and some 1,800 mb think of restarts your PSP (or remove the battery stay long press the power button) and resume normally once the psp show 29 GB (Giga 3 under the formatting, do not be surprised). In short I am satisfied plus it makes a big economy because a true memory stick 32GB would cost a little more than double ... so it is widely available;)
