I was going to use this in the setup of my Grizzly G0715P table saw. However, I never figured up how to configure the tool for me to use it for this purpose. Consequently, I went back to the Grizzly home page and rewatched them demonstrating checking the blade and miter gauge slot. I ended up using a combination square, like the Grizzly employee demonstrated. This was a waste of money for me, however, the look, feel, and adjustment capabilities would very likely make this a fine tool for someone with more know how than me.
