I don't know if this is logical, but based upon my experience with the "power' version of the Fusion razor that was essentially the same as the non-battery powered Fusion device, I would have to hear from several guys that the hassle of another battery powered razor (the Fusion broke down quickly) was matched by a truly superior shaving experience. I am convinced that preparation is more important than the type of razor, although the SH5 is very good, very comfortable and provides a great experience in peeling the peach--and really is my favorite now. I'm not inclined to go the DE route since what I have now has never given me anything vaguely resembling razor burn, cuts or other irritation. So, it's sort of like Lucille Ball's response when they asked her why she never changed up her TV series, "Don't F__k with Success!"
