I've stopped buying Logitech mice for a long time. The quality is good in the past, and in fact, I am currently still using the G1 that is more than a decade old. Despite playing games like Diablo that requires crazy amount of clicks, I am very surprised it lasted this long. Subsequent mice I got from Logitech never lasts from my experience. Some died in less than 6 months, including wireless ones that starts to have connectivity issues.
i did this before... is pretty hard to fix
I fix until... no click sound and is pretty hard to assemble
in the end... bought those omrom switches from ebay.... I just managed to solder it... and tada... using my perfomance mx now
I also replace my right button just in case it fails soon.
I do have 3 extra omron switches... can help solder... but I am slow and need a macdonald meal for 2![]()

If u are not gonna buy a new mouse, then can try the following.
I did and it gave my mouse a new lease of life.

Replaced the Omron switches, those switches fail after a number of times. My mx anywhere mouse got new switches.
This happen to me. So I bring it to service centerAcutally i have the opposite problem with my mouse, double click wont register or sometimes even single clicks doesnt. But i after i close the steelseries (using rival100) software, it work perfectly. My impression is sometimes its a software issue.
You replaced with the JP ones? How's the tactile feel?
Just to chime in, there are mainly 2 types with different operating force(1.47 vs 0.74N). Also, one thing i noticed from the jp switches is that the pin plunger is very slightly taller than mic versions
Thanks. It's about time they spend more focus on mechanical mice with better switches.
Now quite interested in ROG mice but there are not many reviews out there.

I still have the original Intellimouse. I think this is the first M'soft mouse with optical sensor, right after the rubbery ball. Still works well but too bad it's corded. Now sitting in my hall of fame.![]()
Been a few days and this one works well! In 2 hours, it fixed 100 double clicks problem with my old G602. The only major drawback is click-and-drag. Needs several tries still.
Tried one of them before, the GX950. Wasn't too bad until the rubber coating started getting sticky after a year..... X_X then i never touched it again.
There are quite a number of mice out there right now that you can consider. Have a look in Reddit. I won't say too much since I work in a peripherals company myself and may be regarded as up-selling or trashtalking products.![]()
If you have some soldering skill, is best to open up and replace with new switch.
