Just finished replacing all 4 joysticks on both of my controllers and right out of the gate, they work great. I highly suggest plugging your controller into your laptop and calibrating it at https://dualshock-tools.github.io to ensure you have it centered properly (very easy process).If you dont have a soldering workstation, you will need to make sure you get the essentials before attempting this replacement. It takes a moderate amount of dexterity and know-how when it comes to removing the old joysticks, desoldering, and soldering in the new components. I wish I had a desoldering gun for removing the old joysticks because using a focused heat tool and desoldering wick was a biznatch.At minimum get yourself a desoldering gun, a soldering iron, solder, and flux before you get started. Doesn't hurt to have some 90% or higher alcohol available to clean the circuit board if needed.Great product thus far, hope it holds up and myvcontroller drift stays a thing of the past.
