I bought these for my Mayflash F300 thanks to feedback from the Mayflash review community. Almost every review stated that the standard buttons have been replaced with these Sanwa buttons. I received and installed them expecting to feel the difference but they are exactly the same as the stock knobs. I don't know what I was expecting, but the feel of the exact same keys wasn't the same. I left them installed due to the color change from blue to yellow. I also ordered a Sanwa stick and an octagonal boundary plate and I'm sure the plate will feel different, but I'm not sure about the stick at the moment.
