I'm a new construction electrician. I bought a cheaper brand, it worked well enough until someone kicked it and smashed the laser glass. I recently bought this brand although I had not seen them in the field before. I want to say that this laser was the most talked about laser for a whole week. People couldn't believe the price compared to its features. I particularly like the dial for rotating the laser. My older one didn't have this feature but I think for the price I paid for it. I just didn't know what I was missing. The green pops up at 2x4 compared to my red laser, and having the plumb function on the outside of the laser really improved the accuracy. In addition, the charger with 2 batteries saves lives in use. Hope this helps someone.
