Third knobs (1 tech mobility, 2nd bigben ps3pad ...) and finally bought a vibration function so works on GRID RACER I know an old game, but good function keys allow me to pass me on the keyboard to some function everything is "controllable" pad, the F510 is properly seated in my hands (for indication I made a size 9 gloves, if that helps) coterie non-slip, good sensibilitée analog stick + trigger. a good product that I recommend.
