Perfect!

Perfect for mapping keys. I use this app to map the keys on my 360 controller** As well as my Logitech X3D Joystick which does not have an official mac driver so this app was a life saver.
Easy to setup multiple profiles for different games / controllers. User Interface is pretty straight forward. All in all a solid app and well worth the cost.

**as stated in the description some controllers (like xbox 360) will need a valid driver before they can interface with this app.
