Title: Middle vial is a poor design choice
Review: The reason you use a long level is generally to transfer marks along a long surface. One guy holds the level on the mark the other guy makes the next mark. With only one vial in the center, you need three guys - one to read the vial. There used to be lots of two-vial levels on the market with the vials near the ends, where they should be. Seems the jokers in marketing don't understand how their tools are used and figured they could save money by sticking the vial in the center. It's a bad design.
