Review on 📐 Starrett 505A 7 ProSite Protractor for Enhanced SEO by Darby Perkins

Last month (July/2017) I bought all 3 variants offered on Amazon. Both aluminum models are decals. All 3 are identical in accuracy but due to the price difference it is best to use plastic. It's hard to tell what hot, humid, wet, wet weather will ultimately do to a sticker that sits in the bed of your truck or in direct sunlight for three hours. It's great to use aluminum, throw them in your bag and not worry about durability. But I'm only thinking $70 for a sticker! 👎
