In the looks department the MK2 feels much smoother , the logo has slightly changed spacing and the sticker on the back is in korean. As my pal bought his Gp2x from www.gp2x.co.uk he got two sticks and I got the new gph one for helping him out . Both the sticks are much better the the stock. The image is lots darker on the MK2 then the MK1. I have not tryed out what the change to the Joystick has done. So yeah, not lots changed but I still like my MK1 :lol: !
