The case is not the same quality plastic as the original case, making your controller look and feel a little cheaper than a professional OEM controller case. Notch values are close to 0, 45, 90, 135, ., 315 degrees. This is not the same as the original Gamecube controller as these controllers have the octagonal notches slightly clockwise towards the top corners. However, at this price point this is a very good mod for pro controller users who want to play Smash Bros Ultimate with GameCube style notches, especially considering the octagonal gate notches on pro controllers 80+ (on Skins 3rd party) can run ) up to $100 (for first party skins) if you want the mod to be made by a famous modder in the scene.
