Donor switches? The ones that come with most mice aren’t very good, and if you’re extracting them they’re probably not new anyway.
You can buy some online that last much much longer.
I wholeheartedly believe that Logitech is intentionally using the older, rapidly-failing Omron D2FC-F-7N switches to make people buy more peripherals more frequently. Spending an extra 1-2$ on lasting switches should really not be too much trouble when they’re selling fancy computer mice that cost like 100$ now.
I looked up that part number, I don’t know it off the top of my head, just to be clear. This isn’t a niche special interest thing. You use your computer mouse more than you use your car and probably your phone.
My post is about my G604, but it mirrors my earlier adventures with the G700s. When the G604 was announced and then released, I felt like Logitech were actually trying to make a decent product again, and the tiniest bit of tech doomerism got lifted off my chest. Pity that it didn’t last.




















I’ve detailed elsewhere in the thread, but this is about the G604. The G700s was a similar story before it, although it was easier to take apart (with the caveat that it was much more annoying the very first time - two boards are soldered to each other and the guides online instruct you to add a male and female header strip so you can assemble and disassemble it later with much less headache).
Honestly if the new shell had the same textured plastic as the G700s I’d consider my repaired mouse to be damn near perfect.
