I bought a few as a test, and put them on the 2 buttons I don't use. They made some sound difference from original Sanwa buttons, but not even close the the Silent Sanwa foam. The feeling is OK, but not more, they don't make the buttons feel 'numb'. But I guess there is a reason the Sanwa foam and Sanwa silent buttons are always sold out!
Great products and great service as well. The delivery arrived without any problems or defects. The silencer really reduces the noise from button clicks and is easy to install. Would definitely recommend to a friend.
The install was easy on both sanwa OSBFs and Hori Hayabusa buttons (although you have to cut the "wings" with a scissor in order to make them fit in the hayabusas) but while I really enjoyed the feel on the sanwas with silencers installed, the Hori buttons which are VERY short travel to begin with got me a bit dissapointed.
Sure, I have no complaints on the noise reductional abilities on them, but it felt like the travel on the buttons got almost too short. A bit like a "touch button" more than a mechanical one. They're still playable but dont feel as good as they did before.
With that said, I recommend these to everyone thinking of putting silencers in their sanwas, you get the travel a bit shorter on the button, but the feel is intact.
I installed these shiny side down as instructed into Sanwa OBS 30 buttons and they fit perfectly. They seem to stand up well to the abuse of rapid button press games and reduce a lot of the noise. It no longer sounds like I'm an angry woodpecker trying to get through the controller housing. Not totally silent but much, much better.
Well worth investing in spares to keep handy.
Very easy upgrade to add to your existing or new buttons, just a couple of lugs to press in slightly to remove the button head and in these go, they fit like a glove.
Press the button head back on and no more clicking buttons.
Works a treat.
does what it says on the tin its not a total silencer but it does remove a hell lot of noise
