I voted a "4" for the following:
Merkur Progress- Great razor! It's smooth, adjustable, well built and easy to clean. I don't have issues with the blade being out of alignment with both sides.
Merkur 15c- Great razor BUT to mild. Had to put a shim to really get it going. Ah, but when that shim was in its great!! Shaves smooth, easy to maneuver around the face, good grip, easy to care for.
