It was easy enough to install, everything in the box was very helpful. I only changed the shell and triggers, so I didn't need many of the buttons associated with them. The quality is surprisingly very good, you don't feel indistinguishable from the official controller. The only issue I had was that there is no key mapping pad to connect to the board so none of the keys register. The included mapping frame does not include a backing pad, to ensure your key map connects to your board is important as it is not a very specific material the buttons will not work and render your controller useless. I just removed the pad from the old frame and it worked fine.
