I'll let you have a look at the review for greater detail, but can say that in Crysis I can do the following all with the Sandio mouse:
move forward
move backward
strafe left
strafe right
crouch
jump
crawl
sprint
fire weapon
throw grenade
use binoculars
reload
change weapon
use (interact) with objects
zoom weapon
customise weapon
use the nanosuit (needs mouse movement to use properly)
Drive vehicle (forward & backward and steer left and right)
all that and I still have 5 free commands I can program if needed which is very impressive.
The speed the mouse processes the commands is also very good, working as well as a keyboard.
I can heartily recommend the mouse for an off the peg solution for playing games one-handed. I am thrilled with the results and performance of the mouse.
