Ive had this tool since last Christmas. I received it as a gift from my oldest Son and Daughter-in-Law. I just recently started using it on my Table Saw and Miter Saw for setting angles for various cuts. It have found it to be almost indispensable. Ive got the Wixey digital angle finder also but for some reason I like the Starrett better. If you get the change to get one you wont go wrong. Also great for doing trim work, if you need to cut a miter, this is the best way to get the correct angle to cut.
