Works great to move from game to game without having to move any of the games or walk back and forth ever. Guests coming over? Push it into the next room and close the door.
Put a small garbage can, recycle can, and scrap can on the bottom and a little vacuum as well with a crate to hold all of the solvents/cleaners ect. Tools on top, with a couple note pads/markers ect. in the tray area and you're good to go. I've even got the parts tumbler on the bottom too, and an old style keyboard to plug into some of the video games like Crossfire, to change settings and reboot if the coin battery goes bad.
Only thing that is a pain is if it's hard to reach the service outlet from the coin door or the game doesn't have one, but you can hang a nice rolled up extension cord on the side of the handle tray as well.
