package arrived within 10 days and was packed really well. Installing these in original controllers took no effort, the fitment is great. The power supply of my Nintendo 64 is broken so I can't confirm whether they actually work.
Don't buy it. The character starts walking left after 2 minutes of gameplay, then you have pro press L + R + Start and it fixes... for another two minutes. Seller just tells you to do that every time it happens. Crappy thumstick from a crappy seller
