The semi-vertical ones help compared to a standard (horizontal) mouse, but as someone who had a lot of pain, they were not enough for me. For example, I had the Microsoft sculpt mouse, which came with their split keyboard (the main reason I bought it) and still experienced pain. Then I went more vertical to the Logitech Lift which was better, but did not eliminate the pain entirely. Finally, I now use the Evoluent Vertical mouse and now no longer experience pain in my mousing hand.
The only drawback is when I used a standard mouse (totally horizontal), I used to switch hands and use it ambidextrously. Now I obviously can’t switch hands with these mice.
I think for someone who doesn’t experience persistent pain, a semi-vertical mouse may be well enough.








My father exactly. He’s Asian, so I think he feels more removed from the situation, but he worked in the US for over a decade before retiring back here. He’s still 100% pro-Trump, even though we are feeling the negative effects of his tariffs (“He has to put tariffs, he had no choice, look at their economy”), and he even admits things like Good thing I retired before Trump became president otherwise I probably couldn’t get a work visa now. My dad would vote Trump if he could vote.
