Great for unusual carpentry work
The Protractor is easy to use and appears to be fairly accurate. I used it to build a hexagon frame for a hexagon concrete foundation.

Excellent tool to improve your finish carpentry skills
This tool works great when doing finish carpentry on an old out of square building. It makes it very easy to determine the correct angle to set on your miter saw.

Very accurate
Very accurate, I cut a lot of diffrerent angles and this does the job. Also great for saw setup.

The best price/performance for any protractor I've used
I've owned *lots* of protractors over the years. As a woodworker, checking accurate miter angles, etc. is a necessity. This, relatively inexpensive, digital protractor is the most accurate, and easy to use I've owned. I recently built an end table with a cross-hatch frame, and overlapping dado joints. Multiple angles, and dead-on accuracy had to be absolute. This little protractor proved itself with 5 star accuracy. I would definitely recommend.

Works fine, battery door is problematic
It was a pain to get the battery door to release. It would release on one side and get stuck on the other. Was OK once I got it open, but it was frustrating enough that I almost returned it. Now that has opened once, it seems to release fine now. Operates fine and lock works well.

Just what I needed, small enough to use on my drop saw while still being accurate. Reasonably priced and good quality manufacture too.

This works good. Used it for baseboards. Of course no walls are 90 degrees.
