Easy to build and works phenomenally. Tested great on PC, GameCube (great for Gameboy Player), and Switch Online! Haven’t tried SNES yet but I’ll update when I do.

This controller is highly customizable and works flawlessly with so many consoles!
This kit is also an amazing place to start if you are wanting a build a custom controller of your own for your favorite retro or modern console. It is very high quality and very comfortable to play with. It has completely replaced my SNES controller and I have been using it for a lot of PC retro gaming too!

Arrived quickly, instructions are clear, and fairly easy to follow. Minor initial issues getting the ESP microcontroller flashed (my keyboard conflicted, go figure!) but other than that, went together as expected. Had printed out some shells in Blue transparent PETG on my prusa, and the parts fit great. The included shell and buttons are high quality, though I do wish the option to sub in some RetroSix ones that they offer on this site existed, as that might be a more hassle-free option. The included face buttons are a little rough in the shell, and bind slightly. The controller itself doesn't continue to register them or anything, just feels slightly less smooth that it could. I will probably spend some time sanding them down a little as recommended in the guide. D-pad works great, and the included 100g microswitches are much more my jam than the originally installed ones. Keep in mind, neither are going to be squishy like the original SNES controller, but they give you positive feedback, and work great. Thanks guys, this is exactly what I was looking for to play some retro, or retro style games!
