Best controller ever invented.
If it were the best controller ever it would be able to play all genres with ease. Unless you have 7 year old girl hands, the d-pad is not going to work for you with any kind of precision. Playing THPS3 on that console was like trying to take a dump while standing on my head. The controller was also so gimped that one of their own flag ship games (Metroid Prime) couldn't even use both analog sticks due to the fact that the C-Stick was nothing but a little nub. The Z Button was also kind of iffy.
It was a very comfortable controller, but nothing even close to "best ever."
