Rated by: David P. in Kentwood, MI
These protractors are a great size and having the markings laminated between the top and bottom layers prevents them from rubbing off. However, C-thru really needs to limit the markings to each degree rather than every half degree so you can actually tell one mark from the other. A 4" diameter is simply too small for 0.5 degree increments. The older C-thru model this size only had 1 degree increments.
