Great tool for learning, but there are accuracy issues.

The accuracy of this protractor decreases by +0.25ยฐ when the tool is standing on a machined surface. This accuracy issue can lead to fit issues when tight tolerances are required. This tool is just a great tool for basic angle studies and projects that don't require +/- > 0.25ยฐ.

Cons
  • Very expensive

Measuring odd angles

Love the ease of use. I had to saw through several logs, which forced me to calculate odd angles. I tried using a protractor but couldn't get an accurate reading. I bought a digital protractor and it made it a lot easier to mark the right angle for my cut. A really valuable addition to my tool box. No complaints yet!

Cons
  • Ugly packaging

Filled out an invoice for measuring and marking tools

I needed a quick way to determine the corners of several wall corners in my workshop. Close found drywall corners, but not exactly 90 degrees. I am installing the countertop wall to wall and need to trim the ends to fit the corner of the wall. This tool found those corners quickly and they were easy to transfer to the work surface to fit perfectly. I love light text on dark background. A great tool for those who love DIY.

Cons
  • High Price
