Anything to make work easier and more accurate is always welcome. The X3 Laser Level does both, the manufacturer says. It has a knob that allows users to move the laser line up and down for precise placement and three bubble vials to ensure a level line across adjacent walls for hanging corner shelving and other tasks. The tool can be mounted to the wall with 3M Command adhesive strips. Cost: $45. Strait-Line. 800-464-7946. www.strait-line.com.
