The large skates found on an Endgame Gear XM1 gaming mouse ensure undisturbed gliding, reduce the tiring effect of repeated fast movements and help the user to maintain a high pointer accuracy permanently. Although they may be made of durable PTFE, over time even the toughest skates wear off. That\'s why Endgame Gear has provided a replacement. This set includes four replacement feet in white.Please Note:These replacement skates are designed exclusively for the XM1 gaming mice from Endgame Gear. The 100% PTFE skates are experimental skates with the best possible sliding properties. However this may cause the skates to move slightly, but this does not affect their function.XM1 Mouse Skates Specification:SpecificationDetailColourWhiteMaterialPTFEThickness0.8 mmCompatibilityXM1 Gaming Mouse by Endgame GearXM1r Gaming Mouse by Endgame GearPackage content1 set of replacement feet
