i used them once to rewrap my original tail light harness in that webbed cloth material.(not sure what the exact name of material is). they did a great job and it was a fast turnaround. apparently they are one of the few companies that have the machine that can wrap them in the OE type cloth. They said the machine dates back to the 20's and still running fine. however i cant verify their electrical work since i did not buy a harness from them.
