Review on Protractor Horizontal Carpenters Woodworkers Fabricators by Mike Ewing

It seems a little silly that the display is accurate to 1/100th of a degree, but the actual accuracy is +/- 0.5 degrees. It's also a little tricky when trying to find the angle to work with. I mean for the price it's ok and for what it is you don't need less than 1 degree of accuracy. In any case, my miter saw is less than 1 degree accurate. However, the spirit levels are very good. They are pleasantly "responsive" and not sticky like the thick gel some levels have. The concentric circle plane is more useful than I thought.
