About BOSCH GLL40-20G Green-Beam Self-Leveling Cross-Line Laser
81% appreciated the adjustable laser line
I adjusted the location of the laser level to where I needed it to be and was able to make marks on the wall and hang up items knowing that they would be straight.
I can angle the line-laser to work up an angle and maintain a straight line for hanging pictures along a stairway.
86% praised for its precise laser line
I had no issues with the accuracy of the laser while maintaining plumb and level lines.
The laser is accurate, only about 1/16 off in eight feet.
I have noticed that the laser is 4x brighter than red and it lives up to those claims.
85% liked the variety of mounting options, while 15% found them inadequate
I suggest mounting the laser on a tripod for easier height manipulation and throwing the crosshairs on the wall surface being worked on. The laser already has a clamp for mounting.
74% praised the high-visibility laser line
The green laser is immediately visible even in bright sunlight, making installation easy to read.
The green laser has a wider beam that stays visible for longer distances.
