I use a Microsoft notebook mouse because of my hand issue's, their much smaller and easier for me to hold on to. But, the cool thing about them is they have their own proprietary software for remapping the buttons that is remembered when the computer is rebooted.Whenever I mouse left handed I always change the mouse button mapping so I still use my index finger to click and middle finger to get context menus. I also always buy ambidextrous mice.
I just wish Windows 10 would save the mouse button mapping so I don't have to change it every time I turn on my PC.
I know for sure that there are many gaming mice out there that do the same, they can be pretty pricey though.
