Nintendo Switch 2 joycon Dpad and buttons add-on thing

I started playing Crusader of Centy from the switch megadrive (genesis) collection, and quickly realised using four buttons as a D-pad sucks pretty bad.

This kit was kind of expensive but comes with two different stick-on D-pads and two sets of button caps.

I’m only using the + shaped D-pad. I think the button caps might mark the joycon housing over time so I haven’t put them on but so far I’m liking the D-pad and that's really all I wanted anyway.
