The WLMOUSE Ying63 uses Gateron Jade Pro Magnetic switches. These switches use magnets and sensors instead of physical contacts to process actuations, creating a much smoother keypress without bounce or chatter. Includes: - USB-C cable - cleaning brush - user manual - customized ID cards - keycap and switch puller - 4* extra switches - 4* WL custom keycaps The Ying63 is set to 8K polling rate by default and doesn't need to be reduced or altered. It won't affect your system in the same way that high polling rate mice might, nor will it lead to shorter battery life as it would with a wireless device. Mo: Polycarbonate translucent keycaps Ying: Dye Sub PBT keycaps Ling: Double Shot PBT / Side- printed Dye Sub
