Not really but I tried shaving with the mild one (+) and notice how hard it is to tighten it as it really bends the blade. So last few shaves I didn't tighten it all the way and becomes adjustable razor. You can almost loosen it by full turn and still have huge amount of tension where the head will not unscrew during a shave. When you don't tighten it all the way, blade gap increases and blade exposure also increases as the blade is not flexed all the way in sticking out more. Becomes crazy aggressive. You can dial in how aggressive you want. Works great for 7 day growth
