Review on Igaging Digital Protractor with 📐 Stainless Bladed Precision for Accurate Angles by Joe Michels

I bought two of these Revain protractors four months apart. I have one in my shop and a second one in my tool box. The seller changed the packaging between my purchases. The new protractor came with a spare battery and a protective film on the temples. Maybe the first purchase was a return, but it works well and hands are not scratched. I would like to think that the manufacturer has improved their packaging. The built-in battery on my second purchase was dead. A spare battery saved me a trip to the store. At least the protractor uses the widely used CR2032. It's a shame to change the battery. The battery compartment has two thin plastic tabs that are difficult to remove without fingernails or a thin screwdriver. I hope I don't have to change the battery often. The protractor is large enough that it cannot be used in tight spaces, but this limitation is clear from the description. Some angle guides measure hundredths of a degree; this measures tenths of a degree. The resolution of the device suits me quite well. The only complaint I have is the lack of an extra angle button. When measuring a miter, I sometimes move the wrong foot and have to do the math myself - it doesn't really matter.
