MOD-ONE Contoured Mouse Skates are the ultimate mouse upgrade for improved feel and performance. Made from 100% virgin PTFE (Polytetrafluoroethylene), they have been designed with a curved edge to reduce friction and prevent the mouse skate edge from dragging. Thus, achieving a more premium and fluid feel over traditional flat mouse feet. Great for gamers and professionals alike! As mice feet wear their friction increases over time. As this happens, fluidity in mouse movements diminishes requiring the user to adapt to changing conditions. PC Gamers, especially those playing first-person shooters, are most impacted by this as every mouse movement needs to be as controlled as possible. Upgrading to MOD-ONE Contoured Mouse Skates will bring life back into your old mouse and improve feel back to, or beyond, factory condition. Two sets of mouse skates are included in every package along with an alcohol swab to remove any leftover adhesive from the old mouse feet. We recommend removing the old mouse feet and replacing them versus placing the new mouse feet over the originals. Replace mouse skates as needed for maximum performance. 2 sets of mouse skates are included. Model: LG52H-NT
