It can work but it's tempermental
on October 1, 2013
It works great in lower light conditions like indoor but as soon as it has a large light source to compete with it becomes nearly useless (even with their red glasses to boost visibility) ex.used it in a garage to put up slatwall and the garage door was wide open; nearly washed the line out completely (to be fair, I did finish the job using it but I was disappointed in the brightness)
Pros: It shoots level lines, very bright in lower controlled lighting situations, strong magnets for mounting, simple to use.
Cons: Useless outdoors or in bright sources of light, Tempermental if not mounted near perfectly level (if mounted on a slant the laser beams won't level and flash continuously, blinds you as you're working along the level line (spinning 360 degree lasers aren't as obnoxious as this little guy)
Pro Tip: Mounts to photography tripods or lightstands for a cheap, controllable height stand.
