I personally don't plan on using it anytime soon especially at my current level but it would be nice to know in case other people search it up and also in case I actually stick to the game long enough without taking a really long break.
I got mine the other day, although I recommend not leaning on it too heavily. The difference isn't so big it's worth ruining your base over and for me at least it was basically just "You can stream 40 BPM higher now (250 BPM went to 290) BUT you slider break more". It really isn't important for aim nearly as much as speed, which you seem to be playing aim anyways
