Well then, just get the G100s. It's $19 on Amazon:
The microswitch is non-issue. It is trivial to open up the mouse and increase the leaf spring preload to future-proof any fatigue.
You could also buy backup Omrons for cheap:
Honestly, for the long term, the G100s is probably the most serviceable mouse right now. I would not worry about the clicks, at all.
Order spare mouse feet and take a hole-puncher to the bottom feet, like so:
You can imprint the grooves/holes onto a strip of electrical tape so that you can align the hole-puncher perfectly.
Barring Teensy-modded mice, I think G100s has the lowest click latency and the lowest weight out of all good mice currently available on the market. Well, the Zalman/Skydigital could be a contender, but seems to be a lot more hassle.Edited by daniel0731ex - 8/29/16 at 12:51am
