"Okay, Peter. I know this is your first day at the factory, but it's an easy task. All you have to do is pour this green liquid into a small tube. BUT. and that is very important. Don't over-pour and don't under-pour. It's like the story of Goldilocks and Oatmeal. It should be a yuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuy that a human can say that his things are balanced, that's why they call it the level. Don't screw it up, okay Peter?" Unfortunately, Peter screwed it up. I have this well constructed level, but the main purpose of this tool doesn't work properly. Peter didn't pour enough green liquid into the alcohol vial, so the vial is too big to hold Read. Give it back and give Peter another chance. Don't screw it up this time, mkay, Peter? Update (in a week): Revane has replaced this level with one that works as it should. Changed from 2 to 4 stars Still, it's silly when an error passes quality control.
