Review on 📐 EOUTIL Protractor Inclinometer V Groove Magnetic: Accurate Angle Measurement and Versatile Functionality by Ben Balas

The product is easy to use and I assume it's pretty accurate but I haven't tested its accuracy the display ONLY turns on off after 15 seconds of inactivity! What's wrong with these Chinese gadget designers? Can't they turn it off after 3 minutes? I want to use this goniometer to set the angle of the miter saw and this 15 second timer just kills the functionality of this device. When the display goes blank, I have to press the hold button twice to bring the display back. And then the 15-second timer to turn off the display starts again. It takes a speed monster to set the bevel angle on a miter saw or table saw in under 15 seconds. It's not worth my time to return it.
