    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

    Posted by Stormy on 12th Mar 2018

    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

    Nice upgrade

    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.

    Great options

    Posted by David Barber on 13th Aug 2014

    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.

    Wish all buttons had this option.
