First of all, the build quality is top-notch. As you can see from the close-up photos I took, the metal threads are smoothly machined with zero burrs. The 4-pin male contacts have a nice gold-plated finish, ensuring excellent conductivity and stable signal transmission. The biggest selling point for me is the solderless screw-terminal design. Looking at the inside of the connector, there are four individual terminal holes, each clearly numbered (1, 2, 3, 4). This makes wiring incredibly easy and foolproof! You just strip the wire, insert it, and tighten the screw—no soldering iron required. It saves so much time and holds the wires very securely. Furthermore, the waterproof construction is highly reliable. When disassembled, you can clearly see the rubber sealing gland and the tight end-nut. Once assembled and tightened down on the cable, it creates a perfect weather-resistant seal. I feel completely confident using these in wet or industrial environments. Only minor thing: the wire gauge range could be printed on the housing for quick reference. Finally, they arrived neatly individually packaged, which keeps them clean and prevents scratching during transit. Overall, this is an outstanding value for industrial-grade waterproof connectors. Whether you need them for sensor cables, e-bikes, or automated machinery, I highly recommend them! Will definitely buy again. Review: Very good - Very good quality.
