The blades keep with me for a long time (in the winter when I did not shave every two days, the legs also like up to four weeks), so that the value for money is also my point of view more than great! But even in the summer, I use a shave no less than two weeks at a time, until the next one is due.
With the usual disposable razors I often cut myself. This happens to me with the Xtreme 3 rarely, if ever. I can only recommend the product.
