One Thing I will say regarding the Gillette razors of the last couple of generations, you really have to give them a week or so, the first time I shaved with the Mach III I was like " No Thank YOU!" But I tried it again and once your get used to how it works pivoting at the bottom and all they freaking rock and really do make for a better smoother shave... No Shid!
The Power feature works great, it breaks the surface tension as you move the blade across you face, seems to help it move much smoother.
