Review on 📐 Starrett 505A 7 ProSite Protractor for Enhanced SEO by Byron Elliott

This product is not accurate enough for cutting. I opened the protractor and registered it in the driver's seat. That's about 0.75 degrees (yes, almost a full degree) from true 90 degrees. This will make your miter/bevel cuts look open to the naked eye (after mating with the mating piece). i give it back 60€ is definitely not worth it.
