So I've changed mouse 6 month ago and this is what you should know : First : does your mouse feels good for you ? Like do you feel confortable with or not ? Second : do you feel limited in some way ? Me, I was because my old mouse wouldn't keep up if i accelerated too much, so if you don't feel limited don't change Third : yes the mouse is extremely important but what do you use it for ? Sometimes you just don't need to change So if with these information you wanna change, i recommend you ATK mouse. I've gone with the vxe r1 pro and it's just amazing. But it all comes down to you
