These are the only blades I've used that have been a total waste of time. They shave okay for one shave PER BLADE, then start tugging and pulling if I try to get a second shave out of them. At least on beard hair. I shave my dad's head because his hands are a little shaky, and I use these blades because they work fine for 1 shave and I have no qualms using a new one every time with the cheaper than dirt price.
