The Gillette Fusion does offer a good shave, according to a review by Dave Alexander of About.com and the majority of Amazon customer reviews. As of 2014, this razor has an average rating of 4.5 stars on Amazon.
Dave Alexander does note, however, that the Gillette Fusion is not a very big upgrade over the Gillette MACH3 and that its six blades can make shaving somewhat uncomfortable compared to other razors with fewer blades. Nevertheless, most customer complaints about the Gillette Fusion are about the cost of its replacement cartridges, not the quality of the shave it offers. Men who wish to defray the costs of the Gillette Fusion's razors have the option of storing their cartridges in mineral oil, which prevents oxidation from dulling the blades.
