That time a laser level showed me my ceiling was 3/4 inch off

Picked up a cheap green laser last week on a job in Tacoma and ran it across some bedroom ceilings before hanging. One room looked fine by eye but the laser showed the high side was a solid 3/4 inch out of whack. Fixed it with furring strips and shims before putting up any board, saved me from a mess of shims later. Now I run the laser on every ceiling before I start, takes maybe 10 minutes and catches stuff I used to miss. Anyone else using a laser for ceiling flatness checks or are y'all still eyeballing it?

I used to be the guy eyeballing it and calling it good, then wondering why my crown molding gap looked like a smile. Bought a cheap green laser myself and found a ceiling in a rental that was almost an inch out from one corner to the other, no wonder the old drywall had a crack running across it. Ten minutes with the laser beats an hour of shimming later, that part is real. My first laser was so crooked it lied to me though, so check the thing on a known flat wall before you trust it.
