The $50 covers parts (top rated GuliKit TMR joysticks) and my shop time. In a standard Dualsense this upgrade will give you joysticks that last indefinitely, meaning you won’t need to replace them (or the controller) every six months to two years depending on how intense your playing style is. In a Dualsense Edge, the upgrade service I provide will confer stick drift immunity to the two installed joystick modules which means that you won’t have to keep replacing these stick modules for $25.99 (or more) each whenever one of them develops stick drift. While I am based out of Victoria (near Shelbourne and Hillside) I am open to mail-in orders from anywhere in Canada if postage is handled by the customer. Feel free to contact me if you have any questions. Thanks!
