After replacing the standard Hall Effect stick with the higher-end TMR stick, I've also adjusted the circularity, so it won't be overly sensitive. Photo 7 ⇨ Reliable original standard settings. Operation has been confirmed, and there are no issues. In addition to stick replacement, I've also performed controller maintenance, internal and external cleaning, disinfection, and replacement of deteriorated parts on a controller in good condition. The sticks have also been replaced with new ones. There is some minor wear and tear, but no noticeable scratches or stains. After the replacement, I've confirmed that it works comfortably in APEX Legends with the dead zone set to 0, without any drifting. ※ Response curve is the initial Classic. I've adjusted the center value to be within ±0.05 using a gamepad tester. *Regarding APEX Response Curve "Linear"* A note for those who set the response curve to Linear in the controller settings. TMR sticks and Hall Effect sticks in DualSense do not eliminate the stationary state in Linear. With Linear settings and no dead zone, it's normal for it to move slowly, just like a new original stick. ※ We do not accept any claims regarding Linear settings. Thank you for your understanding. This is simply to significantly reduce the drifting phenomenon that occurs during normal use of PS5 games. Other games work perfectly fine, and it's a drift-free controller, so I think it's a good controller for people whose controller sticks often break to have at least one. No price reduction. Instant purchase OK. According to Mercari rules, the person who purchases first will be given priority, even if there are comments from others requesting to purchase or make changes. You can purchase it as is. Please read the profile as well. I don't mainly sell on Mercari, so the number of listings is small (due to high sales commissions and shipping costs).
