Careful that you get a legit tf card, I bought a 1 gig kingston taiwan thinking it would be comparable to my 1 gig kingston japan, but alas, the taiwan (incidentally the one that cost $20 less) is awful. My Ninjapass X9 won't even boot with it and my R4 has problems with it. Even the write speed from the computer to card is terrible compared to the one made in japan.
