Review on 🔋 Woodworking Carpenter Construction Protractor - Battery-powered by Payton Stovall

Doesn't work right out of the box. I knew something was wrong when a simple 90 degree angle didn't show up in the 90 degree configuration. Angles jump from 2 to 700 degrees and everything in between? Movement of the element causes the reader to turn on and off. Sometimes buttons; how on/off works and sometimes not. There are many positive reviews but I cannot confirm my purchase.
