Zesum TMR Joystick Review: TMR Tech for DualSense & Edge

This video covers the teardown of the Zesum TMR Joystick, which uses tunneling magnetoresistance (TMR) sensors instead of potentiometers. I detail the internal components, TMR sensor specifics, and how it fits and performs in both the standard DualSense and DualSense Edge controllers. The unique mechanical design provides a different feel compared to standard joysticks. I also discuss tension and overall performance thoughts.
