I am using Gillette Guard from it was launched. Or I can say that I am using the same from my teenage.
Previously I was using normal razors with normal detachable blades, but those were creating more rashes on my skin.
Then Gillette Guard comes in market and I started to use it and I am getting a smooth and gentle shave from day one to yet now.
Advantages of Gillette Guard I observed are :
Smooth and gentle shave,
Flexible blade which is self adjusting on your face during the shave.
Long life blade and handle.
