Review on 🔌 BTF-LIGHTING 2 Pin Electrical Connector 18AWG IP65 Male Female Connector: High-Quality Extension Cable for Car, Truck, Boat, Indoor/Outdoor LED Strip Lights/String - 7.87in/20cm Length, 22mm Nut - 5 Pairs by Mark Harris

I have bought other Christmas lights prop connectors and I have never had such quality problems. They came in a package, not a box like the others, so it might have something to do with it, but they are deformed. They're made of harder plastic at a 68-degree angle and don't fit together. I can't imagine assembling them outside on a rooftop or anywhere else in colder weather where the plastic is tougher. I couldn't get them to connect no matter how much force was applied and I don't think this issue can be solved for my needs. just buy another brand that i bought before. Maybe it has to do with the shipping but to me it looks like poor quality control as the shapes just don't match. Anyway, I hope the company reads this, they can check with QC and consider putting them in a box to prevent warping.
