Review on Swanson Framing Wizard Layout Tools by Eldrick Carlton

I received this product and decided to test/verify some known good angles. He did well on some, not on others. This tool made me question my other known precision measuring tools. Table and miter saws tested for accuracy. All this after checking and pausing this tool at a 45 degree angle. I'll have to check with the frame design in the near future to be sure!
