Guess I'll join the chorus. My son ordered a 25-foot coax jumper from DXE for his FM broadcast-band DXing setup. It failed a few days later. I checked and sure enough, the shield side was open but I could not tell which connector was the bad one.
He emailed DXE and, other than being astounded that one of their installed connectors could be bad, they were most helpful. They told him to cut off both connectors and send them back, keep the cable, and they would send him a new jumper. Well, when I checked the individual connectors, one did have an intermittent connection to the shield side. Frankly, I was astounded, too. I had never gotten a bad cable, connector, balun, or anything else from them.
Still, they handled it perfectly, as they always have...
