REFR'S tech is quite fantastic just think of the
huge COs they are competing with, and yet are they are
on top tech wise. The reason for this is that, SPD
tech is far superior.Its almost like they have
invented the wheel, very hard to improve upon. I wouldnt
be surprised if a new tech advancment was made petty
soon. As for me Ill take my own advise and buy more !
