Interchangeable hump and button profiles, hot-swappable switches, and adjustable sensor placement let you refine grip support, actuation feel, and movement pivot independently.\nTunable shape\nInterchangeable hump and button profiles let you adjust the contact points that influence grip, stability, and hand support. Fine-tune the shape to better match how you hold the mouse during tracking, flicking, and controlled aim.\nSwappable clicks\nHot-swappable switches let you choose the click feel that fits your preference. Use crisp mechanical feedback for a familiar response or optical actuation for fast input behavior.\nAdjustable sensor\nSensor position can be adjusted to change the pivot point of mouse movement. This helps align cursor motion with the way you naturally aim, track, and flick.\nProduct highlights\n\nTunable gaming mouse for aim refinement\n\nInterchangeable hump profiles\n\nInterchangeable button profiles\n\nHot-swappable switch design\n\nMechanical and optical switch compatibility\n\nAdjustable sensor position\n\nSpecs\n\nProduct type: Gaming mouse\n\nShape system: Interchangeable hump and button profiles\n\nSwitch system: Hot-swappable\n\nClick options: Mechanical or optical switches\n\nSensor placement: Adjustable\n\nWhat’s included\n\nSymm 3 gaming mouse\n\nInterchangeable hump profiles\n\nInterchangeable button profiles\n\nCompatible switches\n","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-pwnage-gaming-mouse-ultra-custom-pro-symm-3-black-1241276366.png?v=1781170454","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-pwnage-gaming-mouse-ultra-custom-pro-symm-3-1241276368.png?v=1781170390","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-pwnage-gaming-mouse-ultra-custom-pro-symm-3-1241276372.png?v=1781170330","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-pwnage-gaming-mouse-ultra-custom-pro-symm-3-1241276369.png?v=1781170034","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-pwnage-gaming-mouse-ultra-custom-pro-symm-3-1241276365.png?v=1781169968","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-pwnage-gaming-mouse-ultra-custom-pro-symm-3-1241276374.jpg?v=1781169910","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-pwnage-gaming-mouse-ultra-custom-pro-symm-3-white-1241276371.png?v=1781169854","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-pwnage-gaming-mouse-ultra-custom-pro-symm-3-nyomi-purple-1241276367.png?v=1781169794"],"price":99,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:55.168Z"},"share_url":"https://firestarter.network/l/lst_eJpOr1WT","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
