I have a small business where I manufacture custom cable assemblies/harnesses. As of now I use 22, 18, and 16 AWG insulated 7 strand wire for 15 assemblies for orders that range from 800-1200 units per year. Each assembly incorporates different types of connector systems (Micro Fit 3.0, Mini Fit Jr, and quick disconnect terminals). This is without a doubt the best investment I could have made. There is a steep learning curve with regards to the setup so be prepared to dedicate an afternoon to learning the settings. But once you understand how to program it, setting up new programs and changing wires takes less then a minute or two. I would buy this even if I only had to make 100 units a year. The machine does have some weight to it and the handles are ergonomically useless. That said, I highly recommend this product.
