Review on 🔌 yarachel 25Pairs / 50PCS Solar Connectors - IP67 Waterproof Male & Female Connector Kit (25 Pairs Solar connectors) by Payton Luna

I was pleasantly surprised by the quality and features considering how affordable they are compared to some others. They have some sort of "semi-locking" mechanism that prevents the nut from loosening very easily when the plug is subjected to stress, excessive movement, vibration, etc. Makes a "whooping" sound when tightened. But if for some reason you need to unscrew the nut, you can still unscrew it with no visible damage. I am very happy with this purchase.
