As an engineer, I always look for precise and easy-to-use measuring tools for my projects .My analysis of this product showed that its a great option for anyone in need of accurate measurements. The starrett C616R gradations are tempered, meaning they are durable and can withstand heavy use. The measurements are clear and easy to read, ensuring even more accuracy in your work. However the downside is that the price is somewhat steep, but it is definitely worth the investment for anyone in the industrial and scientific field..
