No issues at all. Once tightened down, because of the inherent curvature of the top cap and plate, the blade acts like a tension spring. By turning the handle counter-clockwise, you increase gap and blade exposure ever so slightly in whatever increment (s) you prefer. Trust me, it’s still plenty tight when you make that 1/4 turn to increase it’s efficiency. It will not move....Hmmm, wishlist contender; thanks for the review.
How firm is the setting at 1/8 or 1/4 turn? No risk of of accidentally changing the setting while shaving, or putting it away?
