1. INNOVATIVE TMR ELECTROMAGNETIC TECH: Utilizing advanced TMR (Tunneling Magnetoresistance) technology, these joysticks provide high-precision analog control and lower power consumption. It significantly reduces the wear and tear common in carbon film potentiometers, helping resolve chronic drift issues. 2. EXCLUSIVE ANTI-INTERFERENCE STRUCTURE: Engineered with a unique internal shield, this joystick module prevents magnetic interference from controller triggers (such as magnetic linear triggers). This ensures stable centering and smooth, jitter-free aiming during intense gaming sessions. 3. ENHANCED TEMPERATURE STABILITY: Designed to withstand varying thermal conditions, GuliKit TMR joysticks maintain consistent resistance values and signal outputs under different indoor temperatures. Enjoy a reliable gaming experience with minimal calibrating variations. 4. DIRECT REPLACEMENT ASSEMBLY: Designed to perfectly match the original motherboard physical layout. There is no need for complex circuit modifications. Simply de-solder your old joystick and solder GuliKit NS51 module directly onto your compatible controller's PCB. 5. SKU SELECTION & COMPATIBILITY WARNING: 4 distinct SKUs are available—please ensure you select the exact option corresponding to your controller model. Compatible with standard PS5, PS4, Xbox Series S/X, or Switch Pro controllers respectively. NOT compatible with PS5 Edge, Xbox Elite, or Xbox One controllers due to calibration software limitations. Professional soldering skills are required.
