I am a big fan of Bosch tools and own a number of Bosch products including two self leveling cross line lasers. For me, Bosch means quality and performance, so I had high expectations when I ordered this laser square. I was seriously disappointed when I turned it on. There are two major problems: First, the laser lines are faint and difficult to see in normal room lighting. Second, lasers are not square. Not only are they not perpendicular to each other, they are not even parallel to the base edge of the tool. It's about 1/8 inch by 2 feet, so it's not a trivial amount. I have attached two photos showing the problem. I would not recommend this tool, I sent mine back.
