This is a great little tool, I am taking welding classes at the college and for my fabrication class, I needed an angle finder that was easy to carry, compact and accurate. This little tool is all of those. The only thing that keeps me from giving it a 5-star review is that I think that this kind of tools should come with a users manual. Something to explain all the great little nuances and basically explain how to use it,, and all the different ways that you can use it. THen it would definitely be a FIVE STAR ITEM.
