shuttle xpress - animators friend ?

i just got myself one of these:

you can assign every sort of keystrokes with it
unfortunately it doesnt do two buttons at once (like the wacom)
check the settings window
5 buttons
15 states "jogring" (neutral, 7 left, 7 right)
endless jogwheel in both directions

in quicktime i am now able to very very conveniently check out my playblasts
forward backward in various speeds
frame by frame with the jogwheel

in maya i can do the same
but unfortunately maya sort of "stores" the frames you change
so you if you rotate it faster than maya can display the frames
maya sort of plays catch up with you
