Clear Power DCOC-0177-DC 50ft 3 Outlet HD Cord

I spent about two days installing this cord down, over, and up several buildings using 50+ zip ties and mortar cable mounts only to find that one of the slots on the plug end wasn’t cut out at the factory. Unfortunately I hadn’t see this prior to trying to plug something in so even though I was able to cut away some of the plug body from the slot there was still plastic jammed down there only allowing the prongs about half way in. Amazon sent a refund but this poor quality control cost me a weekend and a lot of frustration as I still don’t have power to my shop/garage. I purchased on sale so if I wanted to buy another one I’d have to pay MORE and redo the whole job. I usually inspect items well before doing any kind of work but there weren’t any frayed wires or cut cabling and I thought how do you screw up an extension cord?? Well, that’s how.
