Review on BOSCH GLL30 30ft Cross-Line Laser Level with 360 Degree Flexible Mounting Device and Carrying Pouch - Self-Leveling for Optimal Precision by Lakshmi Pennington

I purchased this laser level to install 6 inch tongue and groove cedar planks on both sides of a 6 foot wide interior T-door. I saw similar levels being used by contractors on our tanning project and knowing it probably wouldn't work well in bright sunlight I decided to install it in the tanning bed on the ladder steps at dusk and reference marks on either side of the T-door at graduated heights. In this application it worked great, projecting a beam that was easily 6 feet wide. I particularly liked the pendulum-style self-leveling feature. I have other Bosch tools that have worked well and lasted a long time. I only downgraded to 4 stars due to limited usage in sunny conditions.
