I have a logitech gaming mouse G1 and it still serves me well. I modified my mouse in hardware so that the right mouse button and left mouse button are exchanged. Since i am left handed, this works better and i no longer have to change the mouse button configuration in windows and games. And sometimes games do not allow the exchange of the left and right mouse buttons. Win win for me. But my mouse was in dire need of new teflon mouse pads, thus last week i ordered a replacement set from corepad gamers gear. The replacement teflon pads i bought come as 10 pieces on a 3M plastic holder. I bought the pads that are designed to replace the logitech MX500/MX510/MX518/MX700?MX900. But work fine with any mouse i would say. http://www.corepad.com/skatez.html After thoroughly cleaning the bottom of the mouse with a general cleaner and after that with denatured cleaning alcohol of 96% pure... Used all 10 pads and i have to say, it is so friction free. When i tap my mouse gently with my finger it skids away as if it was on slightly molten ice. I am really happy with these teflon mouse replacement pads.
