content: I bought the Fusion manual razor and after using the two included cartridges and then seeing the cost of replacement cartridges, I have tossed my Fusion. Replacement Fusion cartridges are much too expensive and the shave one gets from them simply does not justify this kind of expense. I think the pricing of Fusion cartridges is like that of gasoline: we are being milked of every cent we are willing to part with.Another issue I'm concerned about is that the clamshell packaging is dangerous if it is anything like the packaging used for Mach 3 cartridges. The plastic of the packaging will stab or slice you. It is unsafe for most adults. The government ought to force Gillette to design safer packaging.The main reason for giving this product 1 star is the price. I'm not willing to part with $22 to $28 for 8 shaving cartridges.
