I know alot of gamers use mouse pads to improve there performance and i am a gamer too but do you really need a mouse pad for a laser mouse like is it going to improve your gaming or is the improvement so minimal it's better off not buying a mouse pad.
You don't need one. it depends on the quality of mouse and surface of the desk. My mouse is happy enough straight on the desk at home but I use my work mouse on a sheet of paper as it's a cheapo dell.
My G5 is lightning quick on my bare desk, but as I said it depends on the surface. Normally a sheet of paper will sort it out, even if only temporarily.
My G5 works just fine on desk. But I wish I had bought mousepad because desk surface under mose is really worn now. Well to late so still using on desk and not looking for mousepad. Maybe when I get new desk I will also get mousepad.
