I would rate J & M Pattern & Die Co Ltd as average. The company's website, jandmpatterns.com, provides a good overview of their services and capabilities. However, I found their customer service to be lacking. It took them a long time to respond to my inquiries, and the answers I received were not very helpful. The quality of their products is decent, but nothing exceptional. Overall, I was not overly impressed with my experience with this company.
