aim instantly got better after buying gaming mouse

i was using a crappy off brand mouse which was terrible, my best score on hard bots was 2, could never get over 2 no matter how hard i tried.

but today i got a new proper gaming mouse and i hopped into a training match, and i was consistently hitting 7-10 hard bots, idk if its just a placebo effect but i actually think my crappy old mouse was holding me back
