When I tried this caliper set I was impressed by its accuracy and robust build quality. The stainless steel MATERIAL used in the machinist calipers makes it perfect for industrial and scientific applications. It's very easy to use, and the measurements always come out precise .The protective case that comes with it is also a thoughtful touch. The only downside is that the price could be a bit lower, but considering the quality, it's worth it. Overall, i highly recommend this caliper set for anyone in need of dimensional measurement tools..
