It’s not just a soldering iron needed. I replaced the switches on my 17-year-old Logitech MX Revolution and on a newer Performance MX and the old switches are completely impossible to remove from the PCB without snipping away at them and a lot of (careful) force. However I can say that the result was worth it, no more phantom double-clicks. Mouse itself was fine.

Maybe for some of the newer mice it’s an easier ordeal, though.
