Review on Accurate Measurement at Your Fingertips: Inches Stainless Digital Goniometer Definition by Darnell Golden

The long arms will be especially useful for certain projects I have planned. This sensor is easy to use and the quality seems very good. The product description warns of some hardships on the measuring arms, which I think will be a bit awkward to use. So I used 1700 grit sandpaper on my hands to soften the sharpness. It did the trick - good to go. This is a great tool, especially for the price.
