i never buy a mouse like this for q3. to expensive and complicated. and the quality of this mouse go down after some weeks of regular use.

i don't imagine how many time you need to clean up this.

"perfect mouse"

Perfect mouse depends on sensitivity. I for myself figured that a mouse has to have a few attributes to be perfectly playable (again, there is no such thing as a perfect mouse, but a limitless mouse which allows perfect gameplay).

These are the attributes for my mouse:
-Big and for right hand (so there is enough space on it and it has a lot grip)
-Weightleight, my IE3.0 weights less then a 3.0 of other people since I soldered a thin cable on it, with a thick cable the weight of the cable is so heigh that the cable is like always disturbing moving the mouse, with the thin cable its like wireless.
-Enough m/s, ofc this is very sensitivity dependent, you cant run the ie3.0 below 40cm without mouseaccel.
-Enough Dpi - on My sensitivity it doesn't matter since I need less then 400, but for higher you cant use the 3.0 for example.
-Mouse buttons, I hate it if they are integrated in the shell, imo they work better if they are split from the shell. However its a matter of being used to and of the button being used - As more you play, as easier it clicks, my 3.0 is kinda triggering fast nowadays
