Nintendo TMR and Hall joystick upgrade

We will disassemble your Pro controller or your Joycons,
replace the joysticks with smoother TMR / Hall Effect ones that don't get stick drift and last longer,
calibrate it and give it a basic cleaning.
There are no visible changes from the outside. But stick drift will be gone!
The only thing you need to do is send in your controller.
*So far we only do controllers of the first Switch series.
