Another great experience today at Dunker. I was undecided on which options to use to complete a wiring project. John was extremely helpful providing yet another alternative which was actually a safer, cheaper and quicker option to use. He was very thorough and friendly as always. This is why I continue to return to Dunker for supplies. – Dennis W.
