I ordered a mousepad, and before that I played the Logitech mouse on a piece of fabric but it was pretty annoying. Do you notice a big difference? With a mousepad?
Not particularly, but it could "refine" small things like your mouse movements, so it's easier and much easier to move your mouse, since the floor is so smooth with the mouse pad
With a mousepad it is much more convenient to gamble.
A mouse pad makes your mouse run smoother.
A good mouse pad also has a surface designed to keep the mouse from moving too hard, not too easily, so you have better control over it.
