This controller is 100% functional and works with all of the systems described below.

Measuring just 2.13 x 3.4 inches, the Pico Pad by Rectangle Corner manages to pack all the essential buttons of a modern controller into an incredibly compact design.

Would we recommend using it as your main controller? Probably not. But having one around as an emergency backup definitely wouldn’t hurt—especially if your main controller suddenly dies during an official tournament. At that point, you have two choices: take the DQ or pull out the Pico Pad and embarrass your opponent with a victory.

Humor aside, the Pico Pad is also extremely useful for event organizers and enthusiasts. Its compact size makes it perfect for system setup and testing at tournaments, gaming events, or gatherings where you need a quick, functional controller without carrying around a full-size pad.

For more uniqueness, we added some custom designs as shown in the pics.
