Plugged it right in to my PsP with no problems whatsoever, works great and for less than half the price of a Sony made product, i highly recommend!
was very happy with purchase
I bought this to run in my PSP. No problems what so ever! Reads/writes quickly. I have my PSP overclocked and running straight off of the stick. This card works great!
