I for years already use the products of Gilette and was still not disappointing when I personally have a strong beard hair growth and need to keep the corresponding sharp blades that long and I can say that I have never been disappointed with the products of Gilette am with other well known products already. The keeps them sharp and you can use this good without equal hurt. I personally am very satisfied and can only recommend this product. But for all areas of the body used sharp blades which do not cause injury.
