    Decent looking
    Not near as nice as the one it is replacing.
    Cheap plastic rollers. Not heavy brass rollers.
    Does not grip as well - slips.
    Funny that the new employees like it because that do not know how good the older one was - seems to be a fact of life.

    I had one for quick drafting in architecture school that I lost. It's great for making fast parallel lines without a paraliner for quick sketches. Also good for making lines for my kindergartener to practice her letters! The 12" size is better for the latter.
