Its rubbered in familiar way as on mx510, it offers grip familiar to what is on mx series, I don’t remember exactly the feel cuz I did removed that rubber surface due to some experiments with mouse

Hard to image better mouse if comes to shape of IE 3.0, although when im switched directly from mx510, IE felt really uncomfortable for me, with time I started to love the shape of that mice, im haven’t hold nothing better in hand… ok maybe I did but that wasn’t mice

bewere now I cant switch back to mx510 shape its uncomfortable for me same as IE was for me at the beginning

profile of that mice make u pull the box of mouse by fingers to ur wrist, it has good profile for biggest finger on the left, and very comfort place for 2 smallest fingers on the right, back of the mouse is bigger witch can make u feel weird on the beginning but trust me it will help u in future  mice is designed to hold it probably by only 1 finger on the right (same as mx series) but I have no problems with lay there 2 fingers, its way better situation than it was on mx mousses

Front buttons works just perfect, they are ideal for me, eot.

Side buttons was quite weird for me at the beginning cuz the 1 more closer to wrist doesn’t stand up form the box as that much as I do expected, later I realized I did hold mouse in wrong way cause I do have my favorite position of wheel using and I did hold hand to much backward, when I did moved hand more closer to the cord well… side buttons become best from all mousses ive I did used before… on the beginning im cannot understand why 1 of them is standing out way more than second one, now I know its profile for finger o0 and its outstanding

Using sidebuttons might feel like they cheapest chit ever cuz they have way to much backlash and it feels bit cheap, front buttons also do have bit backlash but way les than side ones, it is just a mater to get use to this but they should be made in that point better

Huh this thing is weird  I do love it and hate in same time  step is noticeable and light surface grip very good the best form all mousses, but in mine opinion wheel should be located closer to the cord cuz when I catch mouse in best fitting my hand way I must make more work by finger as it should happen or its happening on mx or deathadder, still its very good in use but unfortunally sometimes happens it switch me back to other weapon cuz I do have binded weapon 4 mwdown and weapon 5 mwup, it wasn’t happening on deathadder at all but here on mx its happening pretty often and beside wheel work very nice and comfortable it make piss ppl of

Tremendous smooth, and good precision, good feel of sensitivity in hand better than deathadder offers, but it also feels deferent than DA, familiar to mx500 feel, and bit less precise than mx510

every do know this mice has really pissing on negative accel, yeah… hate that, on 125Hz is so big that u feel like u moving u hand in water… situations changes when u use 500Hz then its get seriously reduced to a moment when u barely feel it, and this mouse is only 1 where I do see a sense of using USB at rate 1000Hz cause it makes negative acceleration feel bit less than it is on 500Hz, but u must remember negative accel is till here and u cant do not much about it beside turning on positive acceleration in q3

ok it has negative acceleration but im able to do on that mice the same fast shots as on mx510 I feel, aiming after 180 turn look familiar as on mx510 mine crosshair stops always on place where I did pointed out after turn, in this matter I do find it better as DA, it fist mine game play style as mx510 was, don’t know maybe im didn’t a customized with DA enough but mx510 and ie3.0 feels better for me if comes to fast aiming

If someone don’t like light he might remove it really easy
