OK, I was always Gillette so I tested almost every razors they could get out in recent years. And I must confess that here I am won over by these blades adapted (and it is not nothing) for sensitive skin. Let's face it, yes I see a difference with the usual blades, I feel less quickly (and especially less often) this unpleasant burning sensation at the end of shaving. Shaving comfort, it is always perfect, its efficiency is impressive, in a single pass when the blade is new. Side longevity, I confess use blades well after the tape has whitens and shaving is still effective (albeit more passages). So this type of blade pack is very interesting to me, especially since the prices offered by Amazon are also attractive here. I would advise people to test this razor promotional offer to realize its effectiveness and then to buy the blades here.
