Great product! It really helped me out since I have a ID8 twin and had all kinds of issues with the cardreader in them.
So ordered 2 sets and decided to place them into the cabinet themselves. I designed a 3d model to implement the LCD and buttons just behind the shifter. Initially I used the 2 black buttons for "left and right" but I think it'll be better to only use "left" and use the other button for credits, since you have to buy cards and can't use free-play as far as i know.
