I'm an electrician and needed a way to bend 3" rigid tubing accurately because if you kink that type of tubing you can't flip it over pull it out! After a few test pieces to see how bouncy the tube was, I was able to use this digital angle tool to make perfect bends every time! This makes using a standard protractor so much more difficult. I expected a tool that works this well and accurately to be a lot more expensive so I would say if you need a way to accurately determine angles even if you are not level this tool will work great for you!
