So what I have is just a trackball, no mouse. I'm a big fan of this one in particular, but there's a lot of shapes and sizes of trackballs and of hands, so I'd recommend you do some homework to find one that might best suit you.
I thought they were still considered a trackball mouse? Whats that one called? Im looking for one that is comfortable with my big hands and charges with usb C
I would consider a mouse to have a sensor on the bottom, and be a device that you move around your desk. There are lots of mice that also have trackballs on them. This is just a block that you plant down that has a trackball on the top.
Is it easy to take the tracball out to clean it and the insides of where its in? A couple months of using mine I have to take out the ball and clean it but i can literally just push it out with a pencil so its really convenient
