Oh for sure, that thing is a game changer. I used to mess around with chalk lines forever, now I just slap the laser up and go. Total lifesaver on any straight line work.
But come on, it's just a straight line. A chalk line snaps in two seconds and never runs out of juice. The laser is cool until you're waiting on a charge or it gets knocked out of level. Seems like we're overcomplicating a simple task for the sake of a fancy tool.
