I use it for shaving at least twice a week. Then trimming chest, armpits and pubic hair once a week. So every month, month and a half I get one. But with one month I start having to run two times over the same spot to get a proper cut. I even use the subscribe and save feature on amazon so it delivers automatically.
Anyway, I find it a pain in the ass. With this Phillips do you have to replace blades as well, do you know?
