My feedback . I am very satisfied with my injector razors. I would like to try an AC format in the future. One thing that I would have liked in AC razors would be a clone of E2. It is good to have a razor that has all parts connected. If I am not wrong only Cobra razor offered a design like the Injector E2. Also. There are 3 types of injector razor blades. It is possible to cut an AC blade to injector size in case we would like to try something from Ac blades choices.
