The end of the Powerpole connector was delivered fitted upside down. Luckily I had several Powerpole connectors on hand. I had to cut the power pole and assemble it properly. Now it works great. I don't think the maker understands how to assemble the props. I didn't ask for a refund because I was able to use the cable, but I had to because it didn't arrive as advertised. I would not buy these again as they are probably not assembled properly.
