My anecdote is I switched to a vertical mouse[1] and a split keyboard[2] and it solved it for me. I went from constant dull throbbing pain and fear of career death to not even thinking about it anymore. Yay!

Split keyboard did it for me too. It allowed me to correct the whole posture.

I did this too (with a Goldtouch instead of the Freestyle), and it worked... for a couple years. Then I get RSI so severe that it took me off work for 12 months.

In my case, I think it was the bad posture, smartphone use, and laptop use in bed which continued to damage the tendons, despite the ergonomic setup I used during the day at work.
