Surprisingly good quality of sticks, buttons are nice as well.
Delivery is fast, take around 1 week. Both controllers are wrapped in bubble for maximum protection, good one. There are no retail packaging, and I do not really care. Tested on both controllers, Switch recognize them as Nintendo Pro Controller without any issue. Tested on all buttons, all work well except 1 controller's X button which feel a bit hard to press but still work. I have no nfc card to test whether it work. Overall, I will say this is a good purchase as it cost $29 vs $110 original Nintendo Pro Controller. Highly recommend and I might purchase another 2 sets.
