Not terrible but clever pack

My husband has tested 3 types of blade during this week:
Gillette Mach 3 Sensitive pack of 8 (3,11euros piece)
The Gillette Mach3 Pack XXL (12) (2.31 EUR / piece)
The Gillette Fusion ProGlide pack of 8 (4,625 euros each)
For information, he has sensitive skin, rough hair and blades wear generally very fast. It has therefore opted for an electric razor and is an occasional utlilisateur manual razors.

Here it is that the blades slide hurt, several passages are required to leave no hair and he cut 3 times ......
In short, he is disappointed.
However, for fans (can be more flexible hair), the pack 12 is nifty because blades are expensive month and in addition the packaging is very compact. 4 blades are hidden under the first 8. They should have done a pack of 16 to optimize instead.

The Mach 3 Sensitive: It prefers. Effective, they leave the skin soft. Also the green color of the band pleases Sir.

The merger Proglide: This is the razor. Even if the price is twice as high as MATCH3 blades, it's worth. The hair is cut closer in a single pass. The skin is not irritated.
By cons packaging annoyed me .... the cardboard box is great because it avoids the plastic blister but why shut with tape that requires a knife to open ??????? A rethink
