Title: Worth the $45!!
Review: This is a great accessory for builders. I just nail a framing square to a stud somewhere, attach the laser magnetically, slide it up and down to the proper height, and voiala simple swivel laser with the precision of a much more expensive transit level and no clumsy storey pole to deal with.If you get this accessory you will certainly not regret it.
