Great guide. Although I managed to repair the microswitches following this video: https://www.youtube.com/watch?v=82z-OpHd.... That guide is for a Performance MX, but the part about fixing the switches worked for me on the Anywhere MX although the switches are a different model.
Be very careful when opening the switch as it's easy to damage the cover closing mechanism, so when you put it back together it no longer snaps in place. I did that on one of them, and had to use a couple drops of loctite to hold the cover down but it worked out great still. Also when you open the switch be careful about the metal spring inside as it may easily fly out and get lost.
It was a bit fiddly, but it ultimately saved me delivery time and money for new switches, and the buttons now work perfectly again. Plus, if it fails you can always just desolder them and install new ones.
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
