So far I like it much more smooth and precise,you can shift its DPI on the mouse itself theres a button little button above the Wheel it has 6 DPI gears if you will pretty nicewish it had a up/down mini wheel so you could throotle up and down as needed,but you can bind the DPI to hot keys on the keyboard,however a few things annoy me
1. the 3X fire button is locked into doing just that 3 clicks I wish you could change it to another key or something.
2.the next thing is their software only has doesn't have a profile setup like MS Intelli mouse dose so any changes to the Mouse buttons will have to be undone but last time I installed intelimouse program it worked fine on other mice :3
Could be a bit better but in all tis not 40$ freaking bucks for a mouse.
