Thanks to you, we have received high ratings from many people. We specialize in selling high-precision genuine controllers. We are thoroughly pursuing "high precision" and "a state where it can be used with peace of mind" internally, rather than external appearance. [Product Description] Product Name: PS4 DualShock 4 Model Number: CUH-ZCT1J Rare Color [Basic Services] ・Screws are new or clean. ・New sticks [Precise Maintenance for FPS] Each controller is completely disassembled and meticulously cleaned, including the circuit board and fine parts, using an ultrasonic cleaner and absolute ethanol. Parts with defects such as stick drift and poor button response have been replaced as appropriate, and the product has been finished to enable high-precision operation. (Example: Physical precision recovery maintenance such as cleaning the stick substrate and adjusting the sensor) [Operation and High Precision Guaranteed] All controllers are tested after maintenance as follows. 1. Precise numerical adjustment with "DualShock Calibration GUI". 2. Final operation check through actual game play testing of "APEX LEGENDS". [About the Joystick Information ] Generally, a stick error of 7.9% or less is considered excellent. [For FPS Gamers] In FPS games, if the dead zone setting (e.g., "Linear" setting in APEX) is set extremely low, unintended movements (drift phenomenon) may occur due to the subtle characteristics of each controller. This is due to controller quirks and is not a malfunction. [Peace of Mind Initial Defect Warranty] In the unlikely event that there is an initial defect or malfunction after the product arrives, we will respond with returns, refunds, exchanges, etc., only before you leave a review. Please be sure to contact us before leaving a review (we cannot respond after you have left a review). When connected to a PC, audio output may be restricted depending on the included cable, settings, or OS. Please be aware in advance if you intend to use wired earphones. If you have any questions, please feel free to comment.
