Four Ginful PS4 TMR sensors, 120gf each. Compatible models: All official controller models. #NoteP4parts (View various PS4 controller peripherals.) Performance comparison: Gulkit TMR → (performance is almost the same as Hallpi) Hallpi → Ginful, K-silver. Please understand that Hall effect sensors and TMR sensors are different. Compared to Hall effect sensors, they offer higher precision, lower noise, and a longer lifespan. 120gf refers to the stick's push-down force, and for FPS users, increasing this force can prevent accidental button presses. The standard is 100gf. ※ A separate listing offers regulators compatible with PS5 and PS4 (Edge requires a dedicated one). Installing this further improves stick precision; consider it if your budget allows. Because it's a digital system, the parts don't make contact, reducing drift caused by wear. Instructions for using the software adjustment tool are available on YouTube, and I will provide the link via the transaction message after purchase.
