The part nobody talks about is how a tool like that changes the whole job setup, not just the readings. Half the time on something like car doors is usually you and your partner going back and forth, one guy holding the level, the other second guessing it, rechecking, arguing. When the tool just gives you a number you trust, the two of you stop burning hours on that back and forth and the real cost savings show up there. $600 feels dumb until you do the math on labor for a 14 floor tower. Curious if your callback was different because the readings held up or because you just moved faster the first time.

My old roommate taped his backup codes inside a cereal box and then forgot which box, so he just ate cereal for a month hoping to find them. Never did print mine either, they're sitting in a draft email I sent to myself back in 2019.
