I have this same angle finder and it's a great addition if you're into precise angles for bevels and bowls and such on the scrollsaw. The only problem I have is not product related, but that my Hegner table is aluminum so the magnet doesn't stick to it. I have to use a long piece of tape across the top and sides of it to hold it in place while I tilt the table. I don't have a strong enough magnet to put under the table to make it stick. Very pleased with the product itself though. Worth the price I say.
