Just started with a SE. Compared with a double edge, what is the life of a SE?
Ted Pellas and Walgreen Personna blades are coated stainless and last me 5 to 7 shaves. The CVS brand SE Blades and Treet blades from Rite Aid are not coated and for me start to darken (rust?) after about 3 shaves, they are still sharp but I don't trust using them after they change color.
