I went to HD and got the green Dewalt kind, that was the only thing they had in stock.
I don't think it saved me any time, but I was trying to figure it out with the stand and all. It did tell me that the floor was not level but the ceiling was. It also saved my bacon because I measured the length of the back wall and centered it.. but when I looked at the laser it was off center with the lights in the ceiling. Turns out the lights were centered with the "cut out" of the desk which was in between two columns (out of view in the photo) and the wall extended about 6" beyond the right column. GC said center it with the lights which looked better.
And as Steenland said, people who saw me using it were impressed and I think that showing confidence that everything is "laser straight" .. thinking I'm going to use that as my slogan... "Tyler Signs,
Laser Straight!"
