thread on our local vrzone forums. i must say the newer fakes are
of reasonable quality. knowingly bought a 2gb one months ago when
the price difference between a genuine and a fake one was large.
could fit inside a psp like any genuine stick, run games without
lag, but could not fit into an adapter, and transfer speed was
slower. there's not much to worry quality-wise about the newer
fakes, unless of course you are worried about getting scammed.
