Review on 🔍 Bosch GLL40 20G Green Beam Self Leveling Cross Line: Precision and Efficiency Combined by Brian Diaz

Sure, the green laser is brighter, but it doesn't make sense that the "upgrade" version loses two important features. First, you cannot switch between vertical laser, horizontal laser, and both together. Second, there is no way to turn on the laser when the pendulum is locked. Both features were available in the previous iteration. This model only has: move/unlock the pendulum+turn on both lasers; and move/turn off both lasers and lock the pendulum.
