A few downsides, 1 was that the L and R triggers did not fit as well as the ones that came with the case and got stuck when pressed. 2, the A and B buttons, I had to grind down the underside center quite a bit so that they would actually function.

Button look good, fit good, but for one reason or another they feel a little werid. The feeling only happens if you have the new set and the old set from nintendo side to side, you can feel which one is the nintendo set right off the bat
Bought the black buttons to replace the gray buttons. Poor reproduction that alters how tactile the buttons feel. The L and R buttons are missing a small nub that forces you to have to push the buttons harder to register a signal. The power switch has a random tabs that the gray buttons didn't have and would not fit into the slot of the case. The tabs had to be shaved off for it to fit. See attached photos.
Great quality! Very happy
