This is THE BEST turbo controller available for the nes. It's very comfortable, it has grips like modern controllers, and the cycloid control pad protects your thumb from blisters (although it's NOT a real analog controller, there aren't any NES games which use analog controls anyway). It's especially good for top down action/shooter type games (e.g. Zanac, Jackal), and side scrolling shooters, like Gradius.
