Advertencia de falsificación Medium riesgo
Fake Sanwa buttons exist on AliExpress and Amazon marketplace sellers. Genuine Sanwa has SANWA logo clearly molded inside the button rim, consistent spring feel, and smooth microswitch action. Fakes often have scratchy feel, inconsistent actuation, and blurry or missing logos. Buy from Focus Attack, Arcade Shock, or authorized dealers.

Lo que dicen los usuarios
“Sanwa OBSF-30 for speed and sensitivity. The 0.85mm travel is insane — you barely touch them and they activate. Seimitsu if you want a bit more resistance so you dont accidentally press during neutral.”
