Works great so far.
This does the job really well! I`ve been using Joystick Butter for a while and decided to try this. I think this is just as good and for a fraction of the price. I recommend adding this to a syringe and apply with that. A pack got me about 1mL into my syringe, which can lubricate at least 10 joysticks.
The grease seems to be doing its job keeping the analog stick moving smoothly. The tube comes with plenty of grease at least enough to do two or so controllers. Overall it is a great add-on purchase if you are getting replacement gears for your N64 controller.
