I have a spare G604 in a drawer and my first one has new switches, a new scroll wheel, and a new 3D printed shell to replace the crumbling rubber original.

It’s damn near perfect for me, especially the device switching button being so accessible. Getting it to work despite the planned obsolescence isn’t that much effort all things considered.

I’ll admit the switch replacement surgery is unnecessarily complicated for a fucking computer mouse. Way too many interlocking parts. If you still have it in a drawer, I really think it might be worth looking into it.
