I purchased the Harbor Freight hydraulic crimper in March of 2010. Shortly after receiving the crimper, I notified Harbor Freight about the incorrect die sizes. The customer service agent acted surprised. To correct the situation, Harbor Freight sent me a new set of dies. The new ones I received were the exact ones that came with the crimper. I gave up. Adam is correct that the larger dies will only crimp about a #4 or #2 lug. I would be interested in knowing if the larger dies on the Chinese version would fit the Harbor Freight crimper. If so, does anyone know if they are available for purchase. Larry Gregory
