I highly recommend this type of product for the following reason: - Having used my razor simply by brushing after each use, I was taken him to change the head almost every 3 months! - One day I bought a little by chance this product by using it from time to time. I noticed immediately that the cut was better. Now I use about 1 to week and I change the head every 6 months now. So yes, this product allows for real savings, when we know the price and the heads that spray blower (5-6) to a life of about 1 year! Looks like another: there is no photo ;-)
