I’m not an extremely tech savvy person, like building and saudering and whatnot, but these guys hooked me up with a fully functional piece of machinery, I needed no adjustments with this thing such as what they noted in what I read on the website that I may need to change a capacitor or resistor or something. The cart dumper worked right out of the box but I was sad that I had to make a second order for the nes adaptor because they didn’t have any at the time I bought the dumper . That shipping isnt cheap. Other than that, this is a great product, sleek, and looks great and works great. A little reminder, if the dumper doesn’t recognize the cart, check the contacts and clean them if they need cleaning.
