As a precision machinist, I couldn't be more pleased with this vise. The precision is impressive, down to the thousandth, making it the perfect tool for industrial and scientific applications. The clamp is easy to move and stays securely in place. The only con I can think of is that it may be too pricey for some hobbyists, but it's worth the investment for serious professionals. Overall, this vise is a game-changer for anyone seeking absolute accuracy in their workholding.
