UCONSMIMO tempered glass mouse skates are designed specifically as replacement feet for the Razer Cobra HyperSpeed. The polished glass surface provides a different glide characteristic from standard PTFE mouse feet and helps reduce drag during gaming, tracking practice, and everyday desktop movement. Polished 2.5D curved edges create a smoother transition between the skates and the mouse-pad surface. Each set includes 2 replacement glass mouse skates featuring a glossy Earth-pattern design for users who want to combine functional mouse-foot replacement with a more distinctive gaming setup. Before installation, remove the original mouse feet and make sure the mounting areas are clean and dry. Align each replacement skate with its corresponding position on the bottom of the mouse before pressing it into place. Compatibility: Razer Cobra HyperSpeed. Please confirm your exact mouse model before ordering. Compatibility with Razer Cobra, Razer Cobra Pro, or other Razer mouse models is not claimed.
