ok so my viper ultimate is having scroll wheel problems. basically if I try fast swiping the scroll wheel up, it'll sometimes trigger scroll down movements. same goes to vice versa.

also sometimes the scroll wheel also "jumps", e.g. scroll one notch up, it registers 2 scroll ups.

after searching in the net, a lot people have the same issues as I'm facing (viper mini and ultimate) and it's likely due to shitty scroll encoder.

I'm looking into any service that provides replacement of the encoder in the mouse itself. e.g. replacing the junk with ttc gold encoder. I wonder if there's anyone provide such service? not worried about voided warranty since it's past the warranty period. not really planning to buy a new mouse also, last time g900 double click issue, g903 also suffered the same, now thought viper ultimate would've fixed the double click issue due to optical switch (it did) and introduces new problems.

i found my cheap G502 replacement, the Basilisk X Hyperspeed, cheap, wireless, upgraded green switches annnddd super easy just replace the single AA battery and you're good to go.
