They should've departed from the Fusion model name. Gillette Dyson, Gillette Flymo or whatever is a bit easier than Gillette Fusion ProGlide with NEW Flexball Technology Power Razor.
How is it? I actually have one at home (belongs to the Mrs) well it's giving a very nice DFS not a patch on the R41 but not too far, reminds me of the Kings ofShave Hyperglide.
The ball is moved on a exposed thin strip of metal which is weird to see in a razor. As anyone who shave either go north-south or vice verse the ball movement is a pure gimmick
