i saw the bottom plate and this thing looks dead easy to disassemble if you wanna swap in kailhs or something too
i'm excited for this mouse, seems all the right decisions are being made
I've used D2F-01F (Japan) in IE3.0 for around 10 years with around 2 years cleaning periods.
G403 with D2FC-F-7N(20M) (China) has needed cleaning after 18 months as well, surprisingly not the left button switch but right one. I clean all at once anyway and this pressing of the switches while spraying contact cleaner into them bends the spring part inside a bit making the switches light, maybe I over did it on the G403 as those turned from quite annoyingly stiff when new to light if not lighter than the 10y old IE3.0.
So it's better to have a good switch stiffness to start with as you can always tweak it later and when cleaning don't go too hard on pressing the switch down.
These newer Omrons are built a little different inside and in China. Less material used, lower production costs.
All the micro switches in existence need a cleaning in 12-24 months as they will start losing connection when pressed, such as double clicking and bouncing contact while pressed continuously.
The contact degrades, oxidizes, dirt, what ever, and needs to be cleaned.
