While laying out the cuts for the next sheet of drywall, I noticed all the J-boxes were not at the same height. (Pro Tip: Do *not* trust the original marks on the framing to set your J-box height. Measure and use a level!)

I'm a perfectionist and the plan was to do a tile backsplash so everything needed to be aligned as the grout lines would only accentuate the different heights. Laser lever to the rescue!
