Super easy installation. just drilled a 24mm hole straight into a box I had laying around and even in a scrappy garage project like that it just popped right in and secured.
Replaced the PS Button on my Venom Stick

I replaced the Playstation-Button on my Venom PS4 stick with the Sanwa OBSF-24. I'm a PC player and I don't want any console logos on my stick, so I replaced it with the Sanwa one. I can't say anything about the durability, because it's not used very often, but it does it's job and was very easy to mod.
Real nice tactical feeling

Only problem is that they are a little it smaller than hori's buttons so if you have a Rap IV they will fit nicely still but you will see a little hole, extremely minor problem but can still be a deal breaker for some

These Buttons are perfect in every way. Solid construction that will last. I can definitely recommend

I replaced the 'options' button on my Hori Real Arcade Stick Pro 4 Kai with this Sanwa 24 button. It feels more positive than the stock button so I am happy with it.
Exactly what it needs to be

No complaints at all. High quality button, fast delivery and neatly packaged.

As well as having a great range of colours, the option to have 2 toned buttons, without buying double and swapping the parts around, is awesome.
