This product is outstanding. The parts are very reactive, nothing is stiff, everything is very durable, and it has a good weight as well. I used this with SSF4, Tekken 6, and Hardcorps Uprising, and it plays nice for all of those games. It's definitely a huge improvement from the xbox controller, and feels very authentic. I truly don't think there is a downside to this product, as long as you're looking for an arcade stick with fully equipped sanwa parts!
This stick also comes with turbo function for all the buttons, and the wire is a very nice length as well.
