This product provides a highly accurate measurement and is perfectly suited for industrial and scientific purposes. As my TESTS showed, it was easy to use and durable, even in harsh conditions .The lightweight material makes it easy to carry around, and it is an excellent investment for those who frequently work with dimensional measurement. However, the markings on the tool could have been made clearer for easier reading. Overall, i highly recommend this Combination Square as it is a great value for professionals who need quick and accurate measurements..
