"You should be congratulated on BlockSim 6. It arrived with barely enough time to put it before my students. They are certainly impressed with ReliaSoft products, having had chance to use Weibull++ for themselves, and shared in the analysis of their paper-clip exercise on ALTA 6 PRO. BlockSim just did everything that they would expect."

Les Warrington
