So, I've seen some say the Valet VC1 is adjustable with the lever on the back. I just got one and I can kinda see what they're talking about but at the same time if I "adjust" it, the blade is held more loosely and kinda wobbles up and down and I'm scared to try shaving with it like that. Will having it against my face stop it from moving, or do I need to just make sure the blade is secured tightly so it doesn't move?
