Razer Basilisk ultimate scroll wheel issues

i had the same issue, none of the above helped. eventually i just tried a little IPA (99% pure alcohol) on it and it seems to have solved the issue,

did not soak it in, i used a brush to drip it in and had the mouse hanging front down, jest let it drip around. i’ll open it up seeing that the battery ain’t what it used to be anyway (needs replacing) and will do a proper clean of the wheel and sensors

Mine started doing this after ~2 years years of use.

for those ppl having trouble with them after only a little while, maybe some dirt got into it during packaging? it s worth trying to clean it. the way i did it you don t have to open it up 

the battery is to the rear, not sure what effect ipa has on  it so best keep the mouse hanging front down while dripping some ipa in there

do this at your own risk though 

hope it helps

So I found the issue with my mouse and hopefully this works for most of you.

I opened up my mouse to clean it and noticed the mechanism for the scroll wheel was actually somewhat loose inside the plastic housing. when I scrolled a tiny bit, the actual mechanism would rotate. I fixed it by jamming a small piece of paper between it and the housing. I apologize for the crustiness of my photos. I’ve had this mouse for a while now

Basilisk v3 Pro Wireless scroll wheel jumping fix - Adjusting the resistance of the scroll wheel sensor(little dial on the bottom of the mouse says Resistance next to it) fixed it for me. I think the scroll wheel uses a digital sensor to determine scroll movement and if the resistance is too high it probably has trouble seeing which direction you are trying to go. I lowered my resistance quite a bit and it 100% fixed it for me. Found the dial when I was about to take it apart. Hopefully this helps.
