Review on 🔌 Effortless 10mm LED Strip Extensions: 42-Piece Solderless L and T-Shaped Connectors for WS2811 WS2812B SK6812 LED Strips by Kendrick Breezy

Just got it in the mail and wanted to test it. They are completely unreliable in establishing communication. They match up quite well with the white corner connectors they came with, but almost never with some of the LED bits I left behind from a recent project. I checked the + and - bands for continuity and it only worked if I wiggled them a little. He was never consistent on either side. You can see in the picture where it looks like the connectors are spaced at different distances and depths to ensure a solid connection. Hopefully this will save someone else the trouble of wondering why this isn't working. I suggest trying something else. I cut and solder my connections. Sending another defective product.
