Jumper pack design is attractive to the eye but not very user-friendly in regards to clamp location and poor quality copper cable leads. After several successful jumps, the jumper box began to fail. Further investigation revealed breaks in the copper leads, from box to clamp, that required repair. I had purchased 2 of the jumper packs and both units failed while servicing customer's vehicles.
