Title: This level isn't level
Review: I only have one data point considering that I bought one level, but the manufacturer specifies this level to be accurate to 0.0005" per inch. I rested one end of the level on a fixed point, set the bubble carefully to the middle and made a mark at the other end of the level. Then I flipped the level over and repeated the same process several times. I consistently got an error of 0.001" per inch. While this might not sound like much, it means that over the 48 inches length of this level, you are off by 0.048". If you are trying to put a line around a room that's level, you could easily accumulate a full inch of error. I don't know if this is normal or not, but I am not very impressed. Maybe I don't understand the intent of this tool well enough?
