Installed these on all of my 1UP cabinets - really good upgrade, especially over the buttons in the older 1UP cabinets such as Golden Axe, etc. Much better feel & quality & response out of these as opposed to the stock 1UP buttons. Just make sure to also buy the related connecting wires too, will make your life easier. 12 inch wires work fine for 2-player positions, but if you have a 4 player cab (like Golden Axe or TMNT), you'll want to make sure to get 18 inch connecting wires for the player 1 & player 4 positions. Used them on my countercade too, and a really big upgrade over my countercade buttons as well. Highly recommended
