Equipped with Hall Effect sensors. Cleaned inside and out, in excellent condition. ◇ Ginfull ver. 7, equipped with Hall Effect sensors ◇ New stick replacement [compatible product] ◇ Alcohol cleaned inside and out ◇ Center adjusted ☆ What are Hall Effect sensors? Unlike analog sticks that detect input through physical contact points, Hall Effect sensors detect input magnetically, so they do not have physical contact points. Therefore, drift due to deterioration is less likely to occur. * Some drift may occur depending on game settings, etc., but this is due to high sensitivity and is not a malfunction.
