I do…mostly. I hit Q and P with my ring fingers instead of pinkies. For AZ;/ and shift and enter I do use my pinky fingers always, except (as I’ve just noticed) when I’m typing a capital A or Z. I seem to almost always hit the left shift instead of the right, so I end up using my left ring finger to hit the A or Z in that case.

Hadn’t heard of this company before; I’m quite interested in getting their (non-trackpad) mouse to replace my Logitech G502 Hero that’s dying. Does anyone know any other companies making open-source (or at least DIY-friendly) mice to compare?
