I couldn't adapt to the fact that, when I click, I have to be mindful of not moving the mouse sideways with the right amount of finger pressure.

I quickly got used to mine. It’s not exactly at a 90 degree angle to the desk, the finger pushes about as much down as to the side, and since it’s a natural pinching gesture the thumb on the other side stops any remaining horizontal force. Just find a mouse that has a good design, I’ve seen some I could never use.

I recently tried it but my muscle memory just refused to cope. I used to do a lot of competitve fps gaming and its hard to imagine a different way to hold a house. I do use a kineses ergonomic keyboard though but adapting to that felt much more normal than the mouse stuff idk why
