We strive to reach the highest possible quality with our Xbox 360 controller restorations. We replace the analog sticks with upgraded standard or hall effect sticks, install new top quality thumb caps, and then use the latest calibration methods to store updated data to the controller memory for near perfect centering. We also solder in new LB/RB switches to restore that "clicky" feel of the bumpers, ultrasonic clean and cosmetically restore each shell, and replace any other wear parts like the button and D-pad membranes and AA battery holders if needed.
