I finally bought one after reading all the reviews, the product is good for moderate use not for professionals I believe, it claims to have a 4 gauge cable (flexible weldering style) it looks a little bit less than that to me but can't prove it with facts, clamps could be better they all have a different tension feel when you squeeze them (bit annoying) it comes inside a heavy duty carton with handles for storage and it's very compact for a 16 footer. Conclusion, a GOOD cosumer quality product if you are not looking and wiling to pay for the very best. I'm satisfied.
