qanbaGravity KS Mechanical Shafts Silent Pushbutton 30mm Snap-in (Boxed (Clear Black D04(8 pcs)

Originally these buttons came on the Qanba 2009. After using them for awhile I liked them so much I bought a set for my Hori RAP 4 Premium so I can have the same feel at events. They're really great buttons. A bit less clicky than Sanwas, but feel good.

I purchased these Gravity KS buttons to replace the Hayabusa buttons that came with my Hori fighting stick alpha. They fit perfectly, are very quiet, and make more of a low thud sound than a click. They are a huge improvement over stock. I thought the buttons were a little concave from the pictures but this is not the case they are convex. Highly recommend if you are looking to reduce noise, or would like to update the look of your fightstick.

Silent, easy to install. They are as advertised. No input lag

The buttons are nice looking with smooth quiet action, unless you use them much or press too rapidly. Due to an add material choice the plastic seems to heat up with friction as you use it and eventually starts binding up in the socket, squeaking and such as it gets worse. Let it cool down and it goes back to normal. Good for use only where the button is not heavily used.
