Review on Get Accurate Miter Cuts With GemRed Digital Miter Saw Protractor MP01 by Charlie Maadhadians

This gauge works as you would expect. Use it to find the angle, record the reading and then set your miter saw's gauge accordingly. It worked well and was easy to read. It is plastic, but it is durable and would survive a drop or two and a little job-site abuse.The only tricky part is that you have to properly select the "mode" that you need. It is not hard, but it is a little confusing. Eventually I got it figured out. The "modes" are for whether you are cutting an inside corner or an outside corner or just making a single cut. To a real carpenter, I am sure this is second nature, but to me a DIY'er it took a few tries to understand.Bottom line: I prefer digital to analog, and if you do as well then this is not a bad choice at all for you.
