Review on General Tools 823 Protractor Increments by Michael Glassburn

Instead of experimenting with different cuts with my saw or blueprint and halving the angle (and then putting it on the corner fence), I can now use this digital gauge by reading the result divide by 2 and set the angle on my miter saw. As anyone who's done some refinishing knows, there's rarely a true 90 or 45 degree angle in a house (hence heel or toe gap corners and/or extensive use of caulk in painted trim joints). This tool doesn't work magic and your miter saw will need to be adjusted for a precise cut, but it certainly makes the process easier. Yes, the manual meter works well too, but my old eyes will surely appreciate the clear digital readings on this product.
